Intelligent Control And Its Application Of The Unstable Process
Abstract:This article mainly discusses the control method for unstable processes with time delay. By introducing a negative feedback, the use of double-loop control structure, in the intima control theory based on the dual principle of freedom PID controller design methods and ideas, and ultimately realize the intelligent control of unstable processes with time delay. Through this method to design a two independently controlled with two adjustable parameters, namely regulation system target tracking features and systems outside interference suppression characteristics, in order to achieve optimal control of the target. This article finally by MATLAB/SIMULINK software simulations easy to confirm that the method has a parameter, for example overshoot time shorter, more precise control and so on.
