摘要
研究了舰船电力推进系统的数学模型及其非线性特性。建立了螺旋桨负载的数学模型。针对舰船多相永磁同步电动机推进控制系统在其参数不确定而导致系统反馈线性化的效果变差,无法达到预期的优化性能,严重时甚至会造成系统的不稳定的问题,本文提出了采用扩展卡尔曼滤波方法对系统进行参数估计的方法,应用非线性系统的逆系统方法对控制器参数进行优化设计,并进行了仿真。仿真结果表明,所采用的方法能够使系统达到预期的优化动态性能指标,提高了系统的鲁棒性,具有较好的实用价值。
Warship electrical power propulsion system is researched, multi-phase permanent magnet synchronous motor propulsion control system has expectant optimal dynamic performance under appointed condition, through modeling of screw propeller load application of inverse system methods of nonlinear system and optimization design of controller parameters, based on the mathematic model and nonlinear characteristics of electrical power propulsion system. The uncertainty of parameters can worsen feedback linearization effect of system, not achieving expectant optimal performance, even make system unstable. The Extent Kalman Filter is adopted to estimate system parameters, satisfied effect is acquired.
