In industrial process control,the practical use of recent control tactics has been behind control theory.Because the most tacticses are complicated.Therefore it is difficult to realize these tacticses with sigle mode.Though PID is widely used,but it can't get the effect of optimal control.In this paper,the fundamental problem researched on is that to use the linear mode of decreased order with time-varying parameter to imitate the complicated nonlinear control system.The self-tuning regulater use PIC16C62X series microprocessor to realize the control tactics and algorithm.Since PIC16C62X series microprocessor has successful internal function and external equipment,so that it enables the hardware circuit of self-tuning regulator very simple,comparing with PID control.The above mentioned self-tuning corrector has more control effectiveness and available range.
