摘　　要：对离散变结构控制理论中的离散趋近律方法进行研究,提出一种新的可期待原点稳定性的趋近律—离散变速趋近律,其特点是与系统状态范数成正比,并能够产生扇形切换区。以变速趋近律和传统趋近律为基础,形成一种具有良好性能的组合控制策略。将该组合控制策略应用于UUV舵机系统的无刷直流伺服电机的控制,仿真结果表明,无论是否存在外部扰动的影响,所设计的控制器对给定位置信号都具有很强的跟踪能力。Research on discrete method of approach included in discrete varistructure control theories is conducted.A kind of new method of approach named discrete variable speed approachable law which could expect origin stabilize is proposed,whose features include directly proportional with system norm and making fan-shaped areas created.A composite control strategy with good performance is formed based on variable speed method of approach and traditional method of approach.The combinatorial control strategy is applied to brushless DC servo motor included in UUV＇s steering gear system,analysis of simulation result indicates that the designed controller has almighty tracking ability to given position signal.
