An Adaptive Speed Estimation Arithmetic Based on Absolute Stability
Shan Qingxiao · Electric Machines and Control Application · 2006
A new general arithmetic to design speed estimation arithmetic of asynchronous motor based on the absolutely stability theorem of nonlinear system is introduced. The well-known MRAS based speed estimation arithmetic is proved to be an oriental implement of it, the problem that the error between observed rotator flux and its real value is difficult to be obtained is also be solved by this method. The validate of the theory is checked in simulation.
