Design and Simulation of CSTR Temperature Control Based on ADRC
Continuous stirred tank reactors(CSTR)are widely used in the chemical industry,and the temperature control inside the reactors directly affects product quality.Therefore,studying its temperature control is of great significance.This article obtains a process model with delay links based on the working mechanism and system identification method of the reactor.On this basis,the principle of active disturbance rejection control(ADRC)was applied to design a system which includes extended state observer and feedback control rate,thereby forming an active disturbance rejection temperature controller.Finally,the entire system was simulat-ed.Experiments have shown that the state observer of the controller can track input signals and disturbance signals.Compared with traditional feedback controllers,the active disturbance rejection system has the characteristics of faster adjustment time,lower over-shoot,and strong robustness.Therefore,the controller has stronger adaptability to the environment.
