PID Tuner gives you several techniques to graphically, manually, or automatically adjust the estimated model to match your response data. This example illustrates some of those techniques. When you import response data, PID Tuner assumes that your measured data represents a plant connected to the PID controller in a negative-feedback loop. In other words, PID Tuner assumes the following structure for your system.
PID Tuner assumes that you injected a step signal at the plant input u and measured the system response at y , as shown. The sample data file for this example, contains three variables, each of which is a by-1 array. The time vector t , runs from 0 to 50 s with a 0. You can import response data stored as a numeric array as in this example , a timeseries object, or an iddata object. This action opens the Import Step Response dialog box.
Enter information about the response data. The output signal is the measured system response, outputy. The input step signal is parametrized as shown in the diagram in the dialog box. Here, enter 5 for the Onset Lag , and 0. Then, click Import. The Plant Identification plot displays the response data and the response of an initial estimated plant. Depending on the quality and features of your response data, you might want to perform some preprocessing on the data to improve the estimated plant results.
PID Tuner provides several options for preprocessing response data, such as removing offsets, filtering, or extracting a subset of the data. In this example, the response data has an offset. It is important for good identification results to remove data offsets. Use the Preprocess menu to do so. For information about other data preprocessing options, see Preprocess Data.
The Remove Offset tab opens, displaying time plots of the response data and corresponding input signal. Select Remove offset from signal and choose the response, Output y. In the Offset to remove text box, specify a value of 2. You can also select the signal initial value or signal mean, or enter a numerical value. The plot updates with an additional trace showing the signal with the offset applied.
Click Apply to save the change to the signal. PID Tuner automatically adjusts the plant parameters to create a new initial guess for the plant based on the preprocessed response signal. In the Structure menu, choose the plant structure that best matches your response. You can also add a transport delay, a zero, or an integrator to your plant. For this example, the one-pole structure gives the qualitatively correct response.
Graphically adjust the response of the estimated system by dragging the adjustors on the plot. In this example, drag the red x to adjust the estimated plant time constant. PID Tuner recalculates system parameters as you do so.
To add a transport delay to the estimated plant model, in the Plant Structure section, check Delay. A vertical line appears on the plot, indicating the current value of the delay. Drag the line left or right to change the delay, and make further adjustments to the system response by dragging the red x.
Adjust the numerical values of system parameters such as gains, time constants, and time delays. To numerically adjust the values of system parameters, click Edit Parameters. Suppose that you know from an independent measurement that the transport delay in your system is 1.
In the Plant Parameters dialog box, enter 1. Check Fix to fix the parameter value. When you check Fix for a parameter, neither graphical nor automatic adjustments to the estimated plant model affect that parameter value. Automatically optimize the system parameters to match the measured response data. Click Auto Estimate to update the estimated system parameters using the current values as an initial guess.
Suppose that in this example you know from an independent measurement that the transport delay in your system is 1. To fix the delay value, check Fix. When you check Fix for a parameter, neither graphical nor automatic adjustments to the estimated plant model affect the parameter value. You can continue to iterate using any of these methods to adjust plant structure and parameter values until the response of the estimated system adequately matches the measured response.
When you are satisfied with the fit, click Apply. The Plant menu reflects that Plant1 is selected for the current controller design. You can now use the PID Tuner tools to refine the controller design for the estimated plant and examine tuned system responses. For this example, export Plant1 , the plant you identified from response data. You can also export the tuned PID controller.

The term "artificial life" describes research into synthetic systems that possess some of the essential properties of life. This interdisciplinary field includes biologists, computer scientists, physicists, chemists, geneticists, and others. Artificial life may be viewed as an attempt to understand high-level behavior from low-level rules--for example, how the simple interactions between ants and their environment lead to complex trail-following behavior.

The Complete Guide Into the World of Companion Planting
Pots, tubs, and half barrels overflowing with flowers add appeal to any garden, but container gardening can serve a practical purpose too. Container gardening is ideal for those with little or no garden space. In addition to growing flowers, gardeners limited to a balcony , small yard , or only a patch of sun on their driveway can produce a wide variety of vegetable crops in containers. Basil , chives , thyme , and other herbs also are quite happy growing in pots, which can be set in a convenient spot right outside the kitchen door. Container gardening also adds versatility to gardens large and small. Plants lend instant color, provide a focal point in the garden, or tie in the architecture of the house to the garden. Place them on the ground or on a pedestal, mount them on a windowsill, or hang them from your porch. A pair of matching containers on either side of the front walk serves as a welcoming decoration, while container gardening on a deck or patio can add color and ambiance to such outdoor sitting areas.

Fits pots cm. There are lots of different types of houseplant, and each one has evolved in a different climate. To give them a good chance of survival you need to match their natural climate, as closely as possible, to the conditions in your home or office. The most important factors are the amount of natural sunlight think desert vs shady forest floor and the amount of water think desert vs rainforest.

Are you looking for a new method of gardening? If so, then companion planting is one direction that you should look into. As the home gardening sector continues to grow, different green-thumbed individuals are coming up with all kinds of new methods, including this innovative technique. With companion planting, you can plant different kinds of plants and harvest them together, and at the right time.
Taking advantage of this when growing vegetables, herbs and flowers is called companion planting. This page explains some of the benefits of companion planting and how to choose good plant matches. Plants like beans, peas and clover can add nutrients to your soil and reduce the need for fertiliser.
Space biology provides an opportunity to study plant physiology and development in a unique microgravity environment. Recent space studies with plants have provided interesting insights into plant biology, including discovering that plants can grow seed-to-seed in microgravity, as well as identifying novel responses to light. However, spaceflight experiments are not without their challenges, including limited space, limited access, and stressors such as lack of convection and cosmic radiation. Therefore, it is important to design experiments in a way to maximize the scientific return from research conducted on orbiting platforms such as the International Space Station.
