PID parameter-control has achieved in lots of fields in the industrial proceeding control,however,as the request of the control system improve,and the control object changed,PID could not present as satisfy as demand.In view of insufficient intensity control over the PID in the time delay inertial system,we compare the combination of IMC and PID cascade control with it in this article and simulation in the MATLAB.Along with robust and anti-interference,IMC-PID is not only easier adjusted in speed and tuned ...
