【摘要】：针对一类带有执行器故障、非线性不确定性以及外界干扰的混沌系统,设计一个鲁棒自适应容错控制器,来实现主从混沌系统之间的同步容错控制。不需要知晓准确的故障信息以及外界干扰的上界,根据自适应律在线估计未知量。结合自适应控制技术,设计鲁棒自适应容错控制器,使得无论执行器是否有故障发生,主从两个混沌系统都能够实现同步。以经典的蔡氏混沌电路系统为例进行数值仿真,仿真结果验证了所设计控制器的有效性和可行性。
[Abstract]:For a class of chaotic systems with actuator faults, nonlinear uncertainties and external disturbances, a robust adaptive fault-tolerant controller is designed to achieve synchronous fault-tolerant control between master-slave chaotic systems. It is not necessary to know the accurate fault information and the upper bound of the external interference, and to estimate the unknown quantity online according to the adaptive law. Combined with adaptive control technology, robust adaptive fault-tolerant controller is designed to synchronize both master and slave chaotic systems, regardless of whether the actuator has a fault or not. Taking the classical Chua's chaotic circuit system as an example, the simulation results show that the designed controller is effective and feasible.
