Nonlinear model predictive control for servo drive control of optical-mechanical complexes based permanent-magnet synchronous motor

The paper proposes a method to synthesize the nonlinear discrete predictive position controller in tracking electric drive control system of optical-mechanical complexes based on permanent-magnet synchronous motor. The technique for constructing mathematical discrete nonlinear vector-matrix model of permanent-magnet synchronous motor in rotor rotating coordinate for vector control is given. The permanent-magnet synchronous motor is operated under conditions of two-mass elastic load. The steps to synthesize nonlinear predictive control algorithms by using extended linearization technique and optimization objective function with convex quadratic programming method are analyzed. Computer simulation results are carried out on MATLAB / Simulink environment. In carried out simulation, the performance of discrete predictive controller in the position loop of optical-mechanical complexes tracking control system is assessed with different kind of control signals and under the influence of external disturbance.
