AIMC(Anti-windup IMC)结构是内模控制与扰动观测器相结合的抗饱和控制结构,为了有效地解决AIMC结构中的抗饱和控制器的设计问题,提出了采用条件技术设计AIMC结构中的抗饱和控制器的方法。分析了AIMC结构是一种二自由度的新型IMC结构,能够同时解决扰动及饱和问题。通过引入条件技术的可行性参考输入的概念,给出了抗饱和控制器的设计方法。给出了运用该方法的一个仿真实例,仿真结果表明所设计的系统具有良好的抗饱和性能及抗扰动性能。采用条件技术设计AIMC结构中的抗饱和控制器,计算简便,在没有引入新的不确定参数的条件下改善了系统的整体性能。该方法是一种很有实际价值的抗饱和控制器的设计方法。

AIMC is constructed by fusion of the Internal Model Control structure and disturbance observer. To solve the design problem of anti-windup controller in AIMC, the design method of anti-windup controller is proposed using conditioning technique. Study is made on the framework of AIMC is two-degree-of-freedom IMC that can solve the problems of disturbance and windup together. Through the concept of realizable reference in conditioning technique, the anti-windup controller design method is given. The simulation example using the design method is also given. The results of simulation show that the designed systems have an evident effect in anti-windup and suppressing disturbance. The anti-windup controller in AIMC was designed using conditioning technique, the calculation is simple, without introducing a new uncertain parameters under the condition of improving the overall performance of the system. This method is a practical design method of the anti-windup controller.
