摘要
鉴于异步电动机模拟风力机系统存在的诸多问题,采用直接转矩控制使得系统具有了简单的结构和控制方法。运用模糊控制优化传统的直接转矩控制技术,使得系统具有了更好的稳定性和动态响应。采用灰色预测方法优化了系统的状态变量,使得系统实时性和精确度大大提高。仿真结果表明,改进后的系统比直接采用直接转矩控制异步电机模拟风力机发电的系统在稳定性、动态响应、鲁棒性和实时性方面都有了较为明显的改善。
In view of asynchronous motor simulation of wind turbine systems exist many problems,making use of direct torque control system has a simple structure and control methods.Using the fuzzy control to optimize the conventional direct torque control technique,making system has a better stability and dynamic response.Using gray prediction to optimize the system state variables,making the system real-time performance and accuracy have greatly improved.The results show that the improved system in the stability,dynamic response,robustness,real-time and anti-interference ability has a marked improvement.
