提出了一种利用非参数频率响应对象模型设计重复反馈控制器的方法。与零相位误差（ZPE）控制器（ASME J. Dyn.系统测量。Control，111，pp. 353-358），该方法具有在设备逆不稳定时提供改进的瞬态性能的附加益处。在此控制器设计过程中，在模型不确定性和所谓的q滤波器的期望频率响应之间建立联系。此外，它将表明，最佳等波纹滤波器是有用的，当设计高阶q滤波器。整个过程在发动机控制应用程序上进行了实验验证。重复控制器被用来确定燃料喷射，火花点火发动机的节气门位置的周期性变化的动态燃料需求。当设计前馈加燃料算法时，该加燃料信息是必要的。
A method for designing repetitive feedback controllers using nonparametric frequency response plant models is developed. In comparison to the zero-phase-error (ZPE) controller (ASME J. Dyn. Syst. Meas. Control, 111, pp. 353-358), this method has the added benefit of providing improved transient performance when the plant inverse is unstable. In this controller design process, a connection is made between model uncertainty and the desired frequency response of the so-called q filter. Also, it will be shown that an optimal equiripple filter is useful when designing high-order q filters. The entire process was experimentally verified on an engine control application. A repetitive controller was used to determine the dynamic fueling requirements of a fuel injected, spark-ignition engine subjected to periodic changes in the throttle position. This fueling information is necessary when designing feedforward fueling algorithms.
