Model predictive speed and vibration control of dual-inertia PMSM Drives

In this paper, the application of model predictive control for speed and vibration control of dual-mass electrical drive systems with permanent magnet synchronous motors (PMSM) is presented. The control methodology proposed here relies on incorporating the drives safety and physical limitations directly into the control problem formulation so that future constraint violations are anticipated and prevented. In order to reduce the computational complexity, the MPC controller is pre-computed off-line in an explicit form represented by a piecewise affine state-feedback law thus requiring only a fraction of the real-time computational power. The proposed explicit MPC controller is evaluated through simulations demonstrating feasibility and high effectiveness.
