摘　　要：从工程应用角度出发,对带阶跃扰动控制对象的无静差控制进行研究。采用无静差标准传递函数、结合所设计的闭环跟踪控制系统结构,推导出各控制环节间的解析关系式及设计参数约束条件。所设计的闭环控制系统克服了常规闭环控制的不足,具有简单实用、参数整定灵活、物理可实现性;仿真结果表明,该系统具有良好的目标值跟踪特性、阶跃扰动抑制特性和克服参数变化的鲁棒性。From the view point of engineering application, zero steady-state error control with step disturbance was researched. Combining with the designed closed-loop tracking control system, analytical relationships between the control units and design parameters constraint conditions were derived using the transfer function standard form. The closed-loop control system is designed to overcome the deficiencies of conventional closed-loop control, has simple, practicability, parameters adjustment flexibility and physical realization. Algorithmic simulation results show that the system has a good target value tracking performance, step disturbance rejection characteristics and overcome parameter variation robustness.
