摘　　要：无模型自适应控制(MFAC)作为一种先进控制策略具有较强的鲁棒性和适应性,但对于具有非自衡能力的受控对象却不能够直接应用此方法。为此,对于非自衡系统提出了基于MFAC的边镇定边反馈补偿控制方案,即对于内回路采用简单反馈环节来镇定非自衡系统,外回路以MFAC作为反馈补偿器来消除系统的静态误差,并且提高整个系统的适应性和鲁棒性。最后,在Matlab-simulink平台上,对非自衡系统的受控对象进行了仿真研究,表明此方法的可行性和优越性。As a new type strategy,model-free adaptive control(MFAC) has adequately adaptive and robustness.However,MFAC could not be used to integral process directly.Therefore,a new scheme is proposed.It is stable system,and MFAC is used as feedback compensation.Single feedback controller with high rate sampled is used in inner loop to stable system.MFAC with feedback compensation is adopted in outer loop to eliminate the static error,and adaptive and robustness for total system have been enhanced.Simulation research in integral process system on Matlab-simulink platform show that this scheme are available and superiority.
