Abstract

This paper proposes a current-constrained control approach on the basis of port-controlled Hamiltonion (PCH) system and deep deterministic policy gradient (DDPG) for permanent magnet synchronous motor (PMSM). PCH system of PMSM views the plant to control from the perspective of overall energy and the interconnection and damping assignment passivity-based (IDA-PBC) control approach based on PCH is single-loop, which has the advantages of simple controller design and fewer adjusting parameters, but causes the problem of overcurrent. The method proposed in this paper solves this problem by setting the coefficient of damping assignment matrix from reinforcement learning of DDPG. First, we give the Hamiltonian model of PMSM. Next, a current-constrained control approach on the basis of PCH and DDPG for PMSM is proposed. Finally, the validity of the method is verified by the simulations.
