摘要:
针对能馈型交流电子负载中负载模拟单元输入电流跟踪精度差以及抗扰能力弱的问题,研究一种扩张状态观测器(ESO)结合改进滑模控制的复合控制策略.为削弱滑模控制的抖振问题,根据幂次趋近率与指数趋近率各自优点提出新型趋近率,设计改进滑模控制器以削减电流稳定时的抖振,同时通过扩张状态观测器对电路参数摄动以及外界扰动进行观测并补偿滑模控制率.最后,仿真实验结果表明本文所提控制方法相较传统 PI控制方案具备更好的电流跟踪能力以及抗扰能力.
Abstract:
Aiming at the problem of poor input current tracking accuracy and weak disturbance rejection ability of load analog unit in energyfed AC electronic load, this paper studies a compound control strategy based on extended state observer ( ESO ) and improved sliding mode control. In order to weaken the chattering problem of sliding mode control, a new reaching rate is proposed according to the respective advantages of power reaching rate and exponential reaching rate, and an improved sliding mode controller is designed to reduce the chattering when the current is stable. At the same time, the extended state observer is used to observe the circuit parameter perturbation and external disturbance and compensate the sliding mode control rate. Finally, the simulation results show that compared with the traditional PI control, the proposed control method has better current tracking ability and antiinterference ability.
