• It is validated that the design of induction machine vvvf control system has its rationality and feasibility . the distinct reduction of switching loss shows the efficiency of the three optimal switching patterns initiated . the research of this paper lays a solid foundation for the research of the high - speed motor control system to be continued
  空载和负载实验表明文中所提出的感应电机调速方案的正确性和实用性，以及三种优化svpwm开关模式在减少开关损耗等方面的有效性，为后续的高速、超高速电机控制打下了理论和实验基础。
