摘要
二阶滑模控制能够有效地削弱传统滑模控制的抖振现象。反演设计能够保证系统的渐近稳定性,但在实际应用中存在"计算膨胀"的问题。为了简化控制器的设计,提出了一种基于反演的二阶滑模控制方法。该方法不仅能保证系统的渐近稳定性,而且使系统具有强鲁棒性。针对反舰导弹参数时变、不确定的特点,文中采用基于反演的二阶滑模来设计控制系统,并以仿真实例证明该方法是很有效的。
The second-order sliding mode control (SMC) can effectively weaken the chattering phenominon of conventional SMC.Backstepping design can ensure the asymptotic stability of system,but it has the problem of the 'explosion of calculation' in the actual application.In order to simplify the controller,this paper proposes a method of second-order SMC based on backstepping.It can make the system not only to be asymptotically stable,but also to have strong robustness.Contraposing the time-variable,uncertain characteristics of parameters of anti-ship missile. the second-order SMC based on backstepping is adopted to design the control system.A simulation example is illustrated to prove that above method is very effective.
