The rigid stabilityrequirement is relaxed by including an appropriately chosen filter in therepetitive controller. The proposed control scheme combines a conventional PI-type current controller with a novel repetitive controller to improve both thetransient and steady-state performance. The stability condition of the pro-posed scheme and variance propagation of noise disturbanceshave been analyzedin this paper. Moreover, a systematic designprocedure has also been addressed.The designed repetitive controller can be easily implemented by microprocessorto its simplicity. A PWM inverter system based on PC-DSPLab is constructed toverify the proposed control schemes. The simulation and experimental resultsshow the effectiveness of the proposed control schemes and prove the accuracyof theoreretic analysis. | zh_TW |
