Abstract: A method to design stabilizing switching law is presented in condition that all controllers in the control system are malfunction. The conic switching law is discussed for nonlinear system. Conditions under witch the switching law ensures stable results are discussed. Numerical simulation results confirm the fault-tolerant effect of the switching law.

Key words: fault-tolerant control, switching law, stability

摘要: 针对所有控制器同时失效的情况,研究系统容错切换律的设计问题,发展了圆锥切换律,分析了系统稳定的充分条件,通过在不稳定控制器之间切换来保证系统稳定的控制效果。基于系统的状态和子系统的运动方向选择控制器,可保证系统具有最快的收敛速度。对于子系统同向和逆向的系统分别作了数值仿真,验证了结论的有效性。
