【摘要】：针对传统移动电站存在励磁、调速控制相互独立、缺乏联系的不足,研究和建立了励磁及机电复合调速非线性模型,提出了基于状态参数双重强跟踪滤波估计的非线性鲁棒综合控制策略.采用双重强跟踪滤波的方法,实现了模型中关键状态参量的间接获取,依据多输入多输出系统的精确反馈线性化、非线性鲁棒控制理论,对励磁、机电复合调速综合控制律进行了推导,并进行了仿真验证.仿真结果表明:负载突变时,强跟踪滤波能够快速跟踪和估计状态参数;在外部干扰存在情况下,通过求解线性矩阵不等式,本文得到的控制律在保证励磁、转速控制系统稳定的同时,能够实现L2增益干扰抑制.
[Abstract]:In view of the shortcomings of traditional mobile power station, such as excitation, speed control being independent and lack of connection, the nonlinear model of excitation and electromechanical compound speed regulation is studied and established. A nonlinear robust integrated control strategy based on state parameter dual strong tracking filter estimation is proposed. The method of double strong tracking filter is used to obtain the key state parameters indirectly. According to the exact feedback linearization and nonlinear robust control theory of multi-input and multi-output system, the excitation is obtained. The Synthetical control law of electromechanical compound speed regulation is deduced and verified by simulation. The simulation results show that the strong tracking filter can quickly track and estimate the state parameters when the load is abrupt, and the control law obtained in this paper can guarantee excitation by solving linear matrix inequalities in the presence of external disturbances. While the rotational speed control system is stable, the L2 gain interference suppression can be realized at the same time.
