Abstract
This paper presents a robust speed control method for a permanent magnet synchronous motor (PMSM) drive. The controller designed from conventional field-oriented vector control method with constant parameters will result in an unsatisfactory performance of a PMSM due to dynamic uncertainties such as changes in load and inertia. In this paper an adaptive self-tuning (ST) observer that estimates dynamic uncertainties on-line has been developed, where output is fed forward as compensation to the PMSM torque. The stability of the observer is studied using the discrete-time Lyapunov theory. A performance comparison of the proposed controller with the constant parameter based conventional field-oriented vector controller is presented though a simulation study, which illustrates the robustness of the proposed controller for PMSMs.
