| 摘 要： | RLS自适应滤波器用于有源滤波器直流端电容电压的控制,克服了用LMS自适应滤波器收敛速度慢和稳态误差较大的缺点,同时对直流端电容电压的控制完全摒弃了传统的PI积分控制,解决了控制参数难以调节及对电路中其他参数的变化非常敏感的问题.稳态和暂态特性的仿真研究比较了两种自适应滤波算法对直流端电容电压的控制及对补偿后的主电流的影响,其中RLS自适应滤波器效果要好得多.

| Abstract: | The RLS adaptive filter is used to control the DC-side voltage of the active power filter. It has better performance than the LMS adaptive filter because the LMS filter convergences slowly and has large error in steady state. The RLS adaptive filter control on DC-side capacitor voltage gets rid of the PI integrator entirely. This solve the problem that the integrator parameters are difficult to be adjusted and are sensitive to the other parameters of the circuit. After being filtered by the adaptive RLS filter, the DC-side capacitor voltage has scarcely any ripple. Simulation results on steady and transient were compared and validate the RLS adaptive filter has better performance. |
