摘要
本文在分析了指数趋近率和变速趋近率的上,提出了组合控制策略,它克服了上述两种趋近率的缺点,结合了其优点。将此离散趋近率方法应用于转台控制系统中,设计了离散变结构控制器。仿真结果表明,本文设计的控制器可以保证并改善系统性能。
Based on the description of the exponential reaching law and variable rate reaching law, this paper proposes a combined control strategy, which overcomes the shortcomings of the two laws and combines their merits. Applying the discrete reaching law approach to flight simulator control system, a discrete variable structure controller is designed. The results of simulation show that the controller designed can guarantees and improve the robust performance of thesystems.
