doi:10.3969/j.issn.1000-1093.2012.07.019

Abstract

Abstract: To take the nonlinear effect of interior permanent magnet (IPM) motors into account, a method of fitting the optimal phase curve in flux-weakening region by BP neural network is presented. The theory of maximum torque per ampere (MTPA) control is analyzed. Considering the voltage and current limits of power inverter, the condition for IPM motors to output maximum torque in flux-weakening region is derived. A BP neural network is constructed to map the motor speed and current amplitude to optimal phase angel in flux-weakening region. Computation and simulation results show that the maximum error between the fitting result of the constructed BP neural network and the result of finite element method (FEM) is less than 1°.
