执行依赖启发式动态规划在同步发电机励磁系统中的应用

摘要

介绍了一种控制同步发电机励磁系统的新方法,即执行依赖启发式动态规划(ADHDP)对同步发电机励磁电压的自适应控制.执行依赖启发式动态规划是近似动态规划(ADP)的一种算法,ADP利用非线性函数拟合方法逼近动态规划的性能指标函数,以获得最优解或次优解.仿真结果表明,基于执行依赖启发式动态规划算法的励磁控制效果优于传统励磁控制的控制效果.%In this paper, a new method, adaptive control of Action-dependent Heuristic Dynamic Programming ( ADHDP ) for the excitation voltage of synchronous generator, is introduced. Action-dependent heuristic dynamic programming, a sort of Approximate Dynamic Programming (ADP), which uses the method of nonlinear fitting to approach to the performance index function of dynamic programming, searches suboptimal solution or optimal solution. Simulation results demonstrate that, excitation system of synchronous generator controlled based on ADHDP is superior to conventional control method.
