摘要：
柴油发电机-整流负载系统是一个多输入多输出的复杂非线性系统，柴油机速度和发电机励磁控制完全耦合。该文利用平均值建模的方法建立了该系统的非线性物理模型，该模型包括了柴油机、同步发电机的主要动态特性以及三相整流桥的非线性特性。该非线性模型进一步简化为带不确定性参数的线性变参数（LPV）形式，并基于稳定性定理提出了一种鲁棒变增益控制器的设计方法，其控制性能用H￥性能指标描述，控制器通过一组线性矩阵不等式（LMI）的数值求解得到。仿真结果表明，该控制器具有良好的跟踪和抗负载干扰性能。 |

Abstract:
The diesel generator with rectified loads is a MIMO complex nonlinear system, in which the control loops of diesel engine speed and generator excitation are completely coupled. A nonlinear physical model of the whole system was presented using the average modeling techniques. It accounts for the main dynamic characteristics of diesel engine and synchronous generator, and the nonlinear phenomena of the three-phase diode rectifier. It was further simplified as a linear parameter-varying (LPV) form with parametric uncertainties. Based on a stability theorem, a robust gain-scheduling control synthesis method was proposed, where the control performance was described as the performance index. The controller can be numerically solved with linear matrix inequalities (LMI). Simulation results show good tracking performances and disturbance rejection abilities of the proposed controller. |
