In order to solve the rotational torque curve fitting problem of three-phase asynchronous motor, an on-line fitting algorithm based on particle swarm optimization is designed. Firstly, the rotational torque model of three-phase asynchronous motor is established by using the Taylor-polynomial model. Secondly, through the particle swarm optimization algorithm and the polynomial evaluation function,...
In this paper, a self-adaptive least square method based on data driven is presented, in order to solve the problem of fitting data with severe outliers in motor testing system. Firstly, the mechanical properties of the motor are given, and the model of T-n curve based on the Taylor polynomial expansion approximation is designed. Secondly, the design process of the self-adaptive least-square method...
