[0055] 1. Selection of actual parameters
[0056] Based on the approximate linear dynamic model of SAPF, the model reference adaptive theory is used to control, the adaptive law to control the SAPF tracking reference model is established, and an adaptive controller is designed, such as figure 1 As shown, the SAPF output can compensate currents such as circuit harmonics and reactive power. At equilibrium (x 0 ,u 0 ) Near x δ =x-x 0 , U δ =u-u 0 , Where x is the actual output matrix of APF, x 0 Is the balance point (the matrix composed of the inductor current and the DC voltage during balance), the simulation variable x δ , U are obtained by
[0057] x δ = x - x 0 u = u δ + u 0
[0058] 2. Input and output
[0059] Actually choose the error of harmonics and inductor current as the input of the adaptive controller. At this time, the output of the controller is any value from 0-1 (theoretically), which can be converted into PWM pulse in a...
