摘要 对于无速度传感器的研究主要针对电动机的矢量控制系统,而应用于直接转矩控制(DTC)系统很少.本文研究基于矩阵变换器(MC)直接转矩控制系统(MC-DTC)应用无速度传感器技术以及将三者融合的技术.讨论了无速度传感器的直接计算方法和模型自适应方法,重点讨论了速度自适应辨识方法与满足系统融合要求的控制策略.仿真实验表明,速度自适应辨识速度高于直接计算精度,动态响应好.同时能发挥MC和DTC的优势,成为一种高性能的交流调速系统. The speed sensor-less is mostly applied to the motor vector control system,whereas seldom to direct torque control(DTC) system.The speed sensor-less technology based on matrix converter(MC) direct torque control system(MC-DTC) and their integration technology are studied.The direct calculation means and model adaptation method of the speed sensor-less are discussed,and furthermore the speed adaptation identification means and the control strategy satisfied with the integrative system are significantly analyzed.Simulation results show that accuracy of parameter identification is higher than that of direct calculation,and system dynamic response is also good.It's a high-powered AC speed regulating system with the superiority of MC and DTC.
