Abstract :
Current control strategy is the key to an active power filter´s compensation effects. An novel optimal hysteresis current controller with variable-band is presented. This paper discusses the principle of hysteresis current control, the way to realize variable-band optimal control, and gives a optimal control law generated from simulation. Simulation effects show that dynamic behavior of the controller is better than controller with no optimal control .The simulation results of also verify that the controller is superior to controller with fixed-band hysteresis.
