Abstract
This article proposes a novel deep deterministic policy gradient (DDPG) assisted integral reinforcement learning (IRL)-based control algorithm for the three-phase dc/ac inverter feeding a resistive–inductive (RL) load. The proposed controller autonomously updates its control gains online without the need to know the system model. Excellent steady-state and dynamic system responses are achieved by the proposed control algorithm with reasonably low computational complexity. Moreover, the important initial stabilizing control problem is solved through offline training that uses the DDPG technique. Details of the DDPG-based training procedures are presented. Experimental results are presented to verify the efficacy of the proposed IRL-based control method.
