Abstract：The problem of output tracking is considered for Buck DC–DC converter system based on adaptive dynamic programming (ADP) algorithms. Firstly, an error system is constructed. Then, a performance index is defined by taking the tracking error and control cost into consideration. Next, the optimal control is obtained by ADP for the Buck converter system, which can achieve the optimal tracking error and control cost. The problem of output tracking is also studied for networked Buck converter system based on ADP. The newly proposed algorithms avoid solving Riccati equation alge-braically and have the characteristics such as simplicity and quickness. Finally, simulation results are given to illustrate the validity of the proposed methods.
