变结构控制系统因为系统一旦进入所设计的滑模面,系统对内部参数的变化和干扰便具有不变性,正因为它这一独特的优势,它在很多领域有着广泛的应用。但是一般的变结构控制因此产生“抖动”现象,使它在具体的应用中受到了很大局限。而准滑模控制为这一难点提供了有效的解决途径,它可以有效地减轻或避免一般滑模控制的“抖动”现象。一、准滑模控制器的设计首先采用到达律具有指数趋近律的变结构控制方式来设计控
Variable structure control system Because once the system enters the designed sliding mode surface, the system has invariance to the change and interference of internal parameters. Due to its unique advantages, it has been widely used in many fields. However, the general variable structure control has a “jitter” phenomenon, which makes it very limited in specific applications. The quasi-sliding mode control provides an effective solution to this difficulty, which can effectively reduce or avoid the “jitter” phenomenon of the general sliding mode control. First, the design of quasi- sliding mode controller First, the variable structure control method of reaching the law with exponential approach is used to design the control
