摘要
为改善交流异步电机伺服系统的动、静态品质,设计了一种自适应模糊控制器来控制逆变器的开关,它是在传统的DTC技术基础上加入模糊控制器,使整个控制器具有较强的鲁棒性和自适应性。通过仿真实验,将其与常规的直接转矩控制系统进行比较,证实了这种模糊控制器具有更好的控制效果。
In order to improve the static and dynamic performances of AC asynchronous motors, a fuzzy controller is designed to control the inverter switch with direct torque control (DTC)techniques. The fuzzy control makes the whole control system have strong robustness and adaptiveness. The simulation results show that the performance is improved compared with the conventional direct torque controller.
