中文摘要：
针对监督控制系统输入受限时的切换问题，利用小增益控制法为系统构造多个控制器，并提出一种新的切换逻辑．该切换逻辑可以避免切换系统出现频繁切换，还可以保证系统不会因滞后参数选取的不当而错失切换到最佳的控制器．文中利用积分输入-状态稳定性原理证明了该切换逻辑可以保证闭环系统的稳定性．最后对一组输入约束小增益控制系统进行计算机仿真验证，仿真结果表明了该切换逻辑的有效性．
英文摘要：
Considering that supervisory control systems are subject to input saturation, the small gain control was applied to the multi-controller of supervisory control systems. A new switching algorithm was presented which could avoid the frequent switching of the system. Meanwhile, the proposed scheme assured that the system would not miss the opportunity to select the best controller because of an improper hysteresis parameter. It was proven that the switching strategy guarantees that all signals in the closed-loop system are bounded and the state of the uncertain plant converges to the origin. The simulation was conducted on an input-constrained small gain control system, and the results were given to show the effectiveness of the method.
