摘　　要：针对一类参数不确定的连续搅拌釜式反应器,使用了一种与被控对象无关的自耦比例–积分–微分(autocoupling proportional-integral-differential,ACPID)控制方法.该方法将系统内部所有不确定因素及外部扰动定义为一个总扰动,建立了以总扰动为激励的受控误差系统,并根据ACPID镇定规则建立了连续搅拌釜式反应器(continuous stirred tank reactor,CSTR)的ACPID控制系统.理论分析了ACPID控制系统的鲁棒稳定性和抗扰动鲁棒性.仿真结果表明了ACPID控制系统的有效性,在CSTR稳态调节控制领域具有重要的应用价值.In this paper,aimed at a class of continuous stirred tank reactor(CSTR)with uncertain parameters,an autocoupling proportional-integral-differential(ACPID)control method is used,which is independent of the controlled system.In this method,all uncertain factors in the system and external disturbances are defined as a total disturbance,and a controlled error system with the total disturbance as excitation is established.According to the ACPID control theory,the ACPID control system of CSTR is established.The robust stability and anti-disturbance robustness of ACPID control system are analyzed theoretically.The simulation results show that the ACPID control system is effective and has important application value in the field of CSTR steady-state control.
