针对离散时间多输入多输出（MIMO）系统，提出了一种带有自适应并行前馈补偿器（PFC）的自适应输出反馈控制系统设计方案。在所提出的方法中，一个静态PFC的参数自适应调整，使增广系统与自适应PFC几乎严格的真实的（ASPR）。因此，即使被控系统的属性在操作期间发生变化，所提出的自适应输出反馈控制系统可以保持控制系统的稳定性。理论上分析了所得到的自适应控制系统的稳定性，并通过柴油机燃烧控制的数值仿真验证了所提出方法的有效性。
In this paper, an adaptive output feedback control system design scheme with an adaptive parallel feedforward compensator (PFC) for discrete-time multiple-input multiple-output (MIMO) systems is proposed. In the proposed method, the parameters of a statical PFC are adaptively adjusted so as to render the augmented system with an adaptive PFC almost strictly positive real (ASPR). Therefore, even if the property of the controlled system changes during operation, the proposed adaptive output feedback control system can maintain the stability of the control system. The stability of the obtained adaptive control system is analyzed theoretically and the effectiveness of the proposed method is confirmed through numerical simulations on a combustion control of a diesel engine.
