experiment 1:The heat exchanger has the approximate transfer function design a PID controller so that the closedloop system has a rise time tr15sec and overshoot MP10% to a step input mand. Use MATLAB and plot its step response, then change PID’s three parameters (K,TI and Td) from large to small respectively and plot the responses, summarize their control effect.1. 由(1)設由上式可得 又由 得 加之 則 則故取 那么又由此可得 綜上所求得連續(xù)PID控制器(連續(xù)PID控制器) 或者
