uad is an adaptive control term that cancels the model uncertainty. The Model Reference Adaptive Control block adjusts the adaptive control term to achieve the desired reference model tracking. Optionally, you can also adapt the feedback and feedforward control gains. Though, for this exam...
上一篇笔记中,Dixon 简单演示了 MRAC 如何控制一个带有未知参数的线性系统,来让它趋近一个已知的的 reference model。 这一篇中,Dixon 用另一个简单的例子演示了 MRAC不可以控制一个带有未知参数的线性系统,而且系统是 controllable and observable的。并表示这种方法还是嫩了些。 之后Dixon 用 adaptive backstepping ...
Model reference adaptive control As the name suggests, an adaptive controller adapts to variations in the process dynamics. And these variations could come from a number of places. For instance, the disturbances that come from the environment might change. Or in some cases, variation just comes ...
In this example, the Model Reference Adaptive Controller block is configured to adjust the feedback and feedforward gains online. Specify the learning rate for this gain adaptation. Get gamma_k = 100; Define the parameters for the adaptive control component of the MRAC controller. The adaptive...
See how model reference adaptive control cancels out the unmodelled dynamics so that a nominal plant model matches with a reference model. A MATLAB®example shows where this adaptive control method is used to control the unknown and undesired rolling oscillations, which can occur in a del...
