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 (Anti-windup IMC) is an anti-saturation control structure combining internal model control and disturbance observer. To effectively solve the design of anti-windup controller in AIMC, AIMC Anti-saturation controller method. It is analyzed that the AIMC structure is a new two-degree-freedom IMC structure that can solve the disturbance and saturation problems simultaneously. By introducing the concept of the feasibility of the conditional technique, the design method of the anti-saturation controller is given. A simulation example using this method is given. The simulation results show that the designed system has good anti-saturation and anti-disturbance performance. Adoption of conditional techniques to design anti-saturation controllers in AIMC structures is computationally simple and improves the overall performance of the system without introducing new uncertain parameters. This method is a very practical anti-saturation controller design method.
