摘要
直接转矩控制(DTC)作为一种新型电机控制策略,使控制系统具有优良的动态调节性能。介绍了DTC系统的基本工作原理和主要组成部分。通过Simulink建立异步电机的六边形磁链控制系统和近似圆形磁链控制系统。对比分析这2个系统存在的问题,引入改进的全速度范围DTC控制方案,仿真结果验证了方案的可行性和正确性。
Direct torque control （DTC） is a new motor control strategy, which makes control system have good dynamic regulation performance. The paper introduces the basic working principle and main components of the DTC system,and establishes hexagon and approximate eirele flux linkage controlliug system model by Simulink. Based on the comparison and analysis of existing problems in these two systems, the paper proposes an improved DTC controlling system operating in the whole speed range. The simulation result verifies the feasibility and the correctness of the proposed scheme.
