摘要
为了实现阀门的快速响应、准确定位和柔性起动及关断,将基于空间矢量调制的直接转矩控制策略应用于电动执行机构。以位置传感器取代速度传感器,实现位置速度的双闭环,详细分析了电机的柔性起动和关断过程,并给出了数学模型。设计出以TMS320F2812为控制核心的新型电动执行机构,仿真和实践结果表明:它有良好的动静态特性。
To realize the fast response, precise position and soft start or shut off a valve, a direct torque control method based on space vector modulation was used for motor control of the electric actuator. Then a velocity sensor was replaced by a position sensor to form the double- loop of the position and velocity. How to start or shut off a motor softly was analyzed, while a mathematics mode was given. The electric actuator of TMS320F2812 was introduced. Simulation and practice results indicated that the performance of electric actuator with the direct torque control method had good flexibility and stability.
