【Abstract】 Based on relay feedback self-tuning technology, self-tuning method of multivariable PID controller for coordinate control system of large scaled fossil-fired power unit is stated. Comparing with existing methods, its requirements on a priori knowledge and model of controlled object are lower; physical,concept is clearer and easier for engineering application. The results of simulation shows that the system offer excellent control quality.更多还原
