| 中文摘要 |
| 在backstepping励磁设计中, 虚拟控制函数的参数缺乏最优约束, 为了克服此不足, 通过坐标变换得到了新的励磁系统动态模型和参数替换律, 结合反馈线性化和最优控制策略, 在不确定参数和外部干扰两种条件下, 给出了具有全状态参数最优控制的鲁棒自适应励磁控制设计方法. 为了验证所提方法的正确性, 以具体军用电站励磁系统模型为例, 进行了仿真实验. 仿真结果表明该方法在保证系统鲁棒稳定性和L2增益干扰抑制的同时, 可明显提高状态参数的收敛速度和优化控制能力. |
| 英文摘要 |
| In the traditional bacstepping design of the excitation system, the parameters in the virtual control function are lack of restrain. In order to overcome this shortage, we transform the coordinates to obtain the new dynamic model and the parameter replacement law for the excitation system. When the uncertain parameters and the disturbances of the system are taken into account, we obtain the robust adaptive excitation control law with all state parameters in restrain. To validate the efficacy, we simulate the control of a military moving power station by applying the proposed method. Simulation results show that this method can guarantee the system robustness, suppress the L2 gain disturbance, improve the convergence speed and achieve the total state-parameter optimum control. |
