Abstract

An efficient design method to improve the control performance of rough controller is presented in this paper. As the input-output data of the history process operation may not be enough informative, extra testing signals are used to excite the process to acquire sufficient data reflecting the control laws of the operator or the existing controller. Using data from the successive exciting tests or excellent operation by operators, the rules can be updated and enriched, which is helpful to improve the performance of the rough controller. The effectiveness of the proposed method is demonstrated through two simulation examples emulating PID control and Bang-Bang control, respectively.
