A Novel Speed Control Strategy for Five Phases Permanent Magnet Synchronous Motor with Linear Quadratic Regulator

N. Venkata Ramana, V. L. N. Sastry
Abstract—The paper proposes the application of linearized mathematical model for five phases permanent magnet synchronous motor with the help of vector control theory. The linear quadratic regulator (LQR) is examined as an optimal speed controller for five phases permanent magnet synchronous motor. The designed linear quadratic regulator (LQR) based control technique is simulated in MATLAB/ Simulink environment and the performance is compared with the conventional PI control strategy. All the simulation studies have led to better and robust dynamic performance in terms of Linear Quadratic Regulator.

Index Terms—Five phases permanent magnet synchronous motor (PMSM), linear quadratic regulator (LQR), PI controller.
