Abstract

This paper describes a discrete linear quadratic speed regulator (LQR) for permanent magnet synchronous motor design. Linearization and decoupling processes of a motor model were discussed. An internal input model was introduced to control algorithm in order to eliminate the steady state speed error caused by step reference speed as well as load torque variations. Simulation tests of the drive system with the PMSM, were carried out in the Matlab-Simulink environment. The designed discrete control algorithm was implemented in a digital signal processor (TMS320F2812) and tested in a setup system. Simulation and experiment test results confirm properly operation of the designed drive system.
