针对三点法导引的遥控制导系统纵向通道进行准连续高阶滑模控制器一体化设计。采用理想准连续高阶滑模控制器，构造高阶微分器对滑模面的高阶微分进行估计，实现整个控制器设计。利用更高阶次的滑模控制来规避由于高频切换控制引起的振抖效应，将其隐藏于控制计算中，而不作用于执行机构。控制计算的过程中只需确认模型是有界的，利用该界限值即可进行其切换控制设计。该设计方法对不确定模型很有效，尤其是对于参数变化范围较大的非线性时变系统，有更好的鲁棒性能。

Longitudinal channel controller for the remote control guidance system by using three-point method is integrated designed, which is called quasi-continuous high-order sliding mode controller. Ideal quasi-continuous four-order sliding mode controller form was given, and differentiator was constructed in order to estimate higher differentiation of sliding mode surface. The high-order sliding mode control transfers high frequency switch control, and hides it in the process, so chatterings are avoided effectively. It is worth mentioning that it is a very effective method for uncertain model, because information about band is enough. Especially for systems with large parameter changes, nonlinear and time-varying, robus performance is shown.
