This paper proposes a proportional–integral-differential (PID) filter-shaped optimal PI tracker for on-line robust optimal tracking control of a system with unknown disturbances. The proposed optimal PI tracker consists of both a modified state estimator and the newly modified equivalent input disturbance (EID) estimator. The main contributions of this paper are: (1) The conventional EID estimator is significantly modified to improve the tracking performances of a system with unknown disturbances; and (2) The improved EID estimator can be simply regarded as a plug-in component of the compensator, to perform on-line optimal tracking control of square/non-square servo systems with unknown disturbances.

用于连续时间系统的 PID 滤波器形状的最优 PI 跟踪器、状态估计器和 EID 估计器

本文提出了一种比例积分微分 (PID) 滤波器形状的最优 PI 跟踪器,用于对未知扰动的系统进行在线鲁棒最优跟踪控制。所提出的最佳 PI 跟踪器由修改后的状态估计器和新修改的等效输入干扰 (EID) 估计器组成。本文的主要贡献是: (1) 对传统的 EID 估计器进行了显着修改,以提高未知扰动系统的跟踪性能;(2)改进后的EID估计器可以简单地看作补偿器的一个插件组件,对未知扰动的方形/非方形伺服系统进行在线优化跟踪控制。
