海洋钻井平台柴油发电机组非线性综合控制器的设计与仿真

Design and Simulation of Diesel Generator Nonlinear Controller for Offshore Drilling Platforms

由于海洋钻井平台电力系统存在强非线性和负载不确定性,为了达到稳频稳压及满足电力需求下最少燃料消耗,运用直接反馈线性化方法,建立电力系统非线性数学模型,同时设计非线性控制器,控制原动机速度和发电机励磁电压,提高船舶电力系统稳定性。最后,利用MATLAB进行仿真试验,仿真结果表明,控制器对电力系统能够起到有效的控制作用。

According to strong nonlinearity and uncertainty of the power system for marine drilling platform, in or- der to achieve steady frequency regulation and minimum fuel consumption to meet the demand for electricity, the method of direct feedback linearization was used to establish the power system nonlinear mathematical model, and the nonlinear controller was designed to control the speed of the prime mover and generator excitation voltage to im- prove the stability of the ship power system. Finally, the Matlab were used in simulation. The results show that the controller can play an effective role in control system.
