Q. Explain about Adaptive Control System?

Another type of control system that makes use of the computer is known as adaptive control, which is functionally represented in Figure. While the block G provides the system output for the system input, the feedback is provided by H and is converted to a digital signal. This digital signal is processed by the digital processor to effect the necessary control. The characteristic feature of the adaptive control is that the characteristics of the block G are changed with time so that, for a given input, the desired output is obtained. Based on the prediction of the performance of the system, the digital processor determines how G is to be changed.
