摘　　要：控制器设计是精密跟踪算法的核心之一,为满足跟踪精度指标要求,构建了基于目标状态估计的复合控制系统,从系统频率特性出发,建立理想位置环模型,着重分析中频段高度和宽度对系统动态性能影响。在满足一定相角裕度的前提下,推导出谐振峰Mr与中频宽度H的近似公式,确定滞后超前控制器的各个参数。利用双线性变换对控制器进行数字化实现,便于工程简化运算,通过实际系统验证,取得良好效果。The design of the controller is one of the cores of the precision tracking algorithm. In order to meet the requirements of tracking precision, a complex control system based on the target state estimation is constructed. The ideal position loop model is constructed based on the characteristics of the system frequency. The influence of the mid-band height and width on the dynamic performance of the system is also analyzed. On the premise of satisfy. ing a certain phase angle margin, the approximate formula of resonance peak Mr and mid-band width H are de. duced, and the parameters of lag-lead controller are determined. The bilinear transformation is used to achieve the digitalization of the controller, which is convenient for the simplification of the engineering operation. It is verified by practical systems, and better effect is got.
