摘要:

将非线性PID控制理论应用于三相电压型有源滤波器的离散控制系统,通过引入非线性跟踪微分器与PID控制信号的非线性组合,推出了基于非线性PID控制的三相有源滤波器的离散控制系统差分方程的迭代格式,并对非线性PID控制的离散差分方程与传统PID控制的离散差分方程进行了MAT-LAB仿真.仿真结果表明:采用非线性PID控制可以显著地改善传统PID控制的快速性与超调量之间的矛盾,提高系统的跟踪速度,具有很好的鲁棒性,且具有很好的滤波效果.

Abstract:

By applying the nonlinear PID control theory to the discrete control system of three-phase voltage type active filter, by introducing the nonlinear combination of nonlinear tracking differentiator and PID control signal, the iterative format of the difference equation of the discrete control system based on the three-phase active filter controlled by nonlinear PID control is introduced, and the MAT-LAB simulation of the discrete difference equation of nonlinear PID control and the discrete difference equation of traditional PID control is carried out. The simulation results show that the use of nonlinear PID control can significantly improve the contradiction between the speed and overshoot of traditional PID control, improve the tracking speed of the system, have good robustness, and have good filtering effect.
