英文摘要
      This article designs a protective voltage regulator for Buck–type converters based on adaptive dynamic programming. Firstly, to achieve output voltage tracking with non-impact inductor current, a standard proportional integral regulator is used in the current inner loop, and a linear quadratic regulator related to output voltage error and inductor current differentiation is used in the outer loop, enhancing the ability of smooth transition of inductor current. Secondly, this regulator adopts singular perturbation theory to achieve separation of fast and slow dynamic models and model reduction, reducing system complexity. In addition, a virtual system is designed between the system and regulator to implement an intelligent data storage scheme, avoiding the use of a large number of finite integral window functions during iterative approximation of the optimal solution of the linear quadratic regulator. The simulation results have verified that the proposed protective voltage regulator achieves precise voltage tracking performance, transient response, and reduces inductance current surge in the presence of unknown model parameters.
