摘    要:
针对一类具有非匹配不确定性的多变量系统,提出了一种递阶结构的高阶终端滑模控制方法.将多变量系统变换为解耦块能控标准型.采用非奇异终端滑模,结合微分估计器,设计高阶滑模控制策略,使输入输出子系统的状态在有限时间内收敛至平衡点,内部子系统的状态收敛至平衡点的邻域内.所提方法可以简化系统结构,消除控制抖振,通过控制器参数和非匹配扰动的上界可以估计系统状态的收敛范围.仿真结果验证了该方法的有效性.

关 键 词:多变量系统  终端滑模  高阶滑模  匹配条件

Abstract:
A hierarchical high-order terminal sliding mode control method is proposed for a mismatched uncertain multivariable system.The multivariable system was transformed to the decoupled block controllable form.Combined with the derivative estimator,the nonsingular terminal sliding mode manifold was utilized and the high-order sliding mode control strategy was designed to drive the states of the input-output subsystem to the equilibrium points within finite time,and drive the states of the internal dynamic subsys...
Keywords:multivariable systems  terminal sliding mode  high-order sliding mode  matched condition
