Research on Motor Speed Estimation Method Based on Electric Vehicle

Abstract

The classification describes common methods for estimating motor speed. Methods completely dependent on the physical parameters of the motor and the electromagnetic equation are easy to implement, but have poor robustness and anti-noise ability. Methods partially dependent on the physical parameters of the motor and the electromagnetic equation are introduced. Simulated and compared Model Reference Adaptive System (MRAS) and Sliding Mode Observer (SMO). Methods independent of the physical motor parameters and electromagnetic equations are introduced. Introduced common artificial intelligence algorithms. The applicability of various algorithms is summarized.
