Study of Input Voltage Anti-Disturbance Control of Matrix Converter Fed Induction Motor Drive System
摘要
Abstract
The influences of input voltage disturbances (including short-time voltage sag and unbalance) on matrix converter fed induction motor drive system are analyzed in this paper, which deteriorate the motor voltage and lower the motor speed. A control strategy which restrains the input voltage disturbances is proposed. Over-modulation technique is employed in this control strategy, which expands the operation range of motor drive system. Experiments and simulations demonstrate that, the motor voltage is compensated effectively and the motor speed is maintained under input voltage disturbances by using the proposed control strategy. The anti-disturbance capability and stability of the drive system are improved and enhanced.关键词
