中文摘要
      考虑了状态受限的非完整单链式系统的实际镇定问题. 利用链式系统的特殊结构设计了两步控制算法. 该方法能够使闭环系统的状态最终收敛到原点的任意小邻域中, 且若系统初值小于任意正数M, 那么除了一个收敛到零的状态变量外, 其余状态变量在整个实际镇定过程中均小于正数 (1+ε)M, 其中ε可事先任意小. 最后对平面移动机器人进行了仿真, 验证了所给方法的有效性.
英文摘要
      This paper investigates the practical stabilizing problem of chained systems with state constraints. Based on the peculiar structure of the chained form system, a new two_step controller is presented, which can stabilize the states of the system to an arbitrarily small neighborhood of its equilibrium in a finite time. In addition, if the initial value of each state is less than or equal to some positive number M, all states are less then or equal to (1+ε)M for an arbitrary positive ε except only one state which exponentially converges to zero. The application of it to a nonholonomic wheeled mobile robot is described. Simulation result shows that the proposed controller is effective.
