三相PWM整流器的哈密顿与滑模协调控制研究
|
摘要
针对三相电压型(pulse-width modulation,PWM)整流器传统单一的控制方法存在的不足,滑模控制的稳态特性较差以及哈密顿控制的动态响应较慢等问题,本文设计了基于滑模和哈密顿控制的PWM整流器的协调控制策略。首先在三相PWM整流器拓扑的基础上建立数学模型,分别设计出整流器状态误差哈密顿控制器和滑模控制器,在此基础上设计出协调控制策略,并分析了系统稳定性,协调控制能达到直流输出恒定和单位功率因数运行目标。仿真实验结果表明,PWM整流器的哈密顿与滑模协调控制能够满足整流要求,同时具有快速的动态性能和优良的稳态性能。该研究验证了协调控制的可行性,为PWM整流器的控制策略的研究开启了新思路。
In order to solve the problems that three-phase PWM rectifier control method is traditional and single,steady-state characteristics of sliding mode control is poor,and control Hamiltonian dynamic response is too slow,coordinated control strategy of PWM rectifier based on sliding mode and Hamiltonian control is designed.Based on the topology of three-phase PWM rectifier,the mathematical model is established,and the state error Hamiltonian controller and sliding mode controller are designed respectively.On the basis of this,the coordinated control strategy is designed,and the stability of the system is analyzed.The control system can achieve the constant DC output and the unit power factor.The simulation results show that the PWM rectifier can meet the requirements of rectification,and has fast dynamic performance and excellent steady-state performance,which verifies the feasibility of the coordinated control.
