【摘要】：針對一類帶有執(zhí)行器故障、非線性不確定性以及外界干擾的混沌系統(tǒng),設(shè)計(jì)一個(gè)魯棒自適應(yīng)容錯(cuò)控制器,來實(shí)現(xiàn)主從混沌系統(tǒng)之間的同步容錯(cuò)控制。不需要知曉準(zhǔn)確的故障信息以及外界干擾的上界,根據(jù)自適應(yīng)律在線估計(jì)未知量。結(jié)合自適應(yīng)控制技術(shù),設(shè)計(jì)魯棒自適應(yīng)容錯(cuò)控制器,使得無論執(zhí)行器是否有故障發(fā)生,主從兩個(gè)混沌系統(tǒng)都能夠?qū)崿F(xiàn)同步。以經(jīng)典的蔡氏混沌電路系統(tǒng)為例進(jìn)行數(shù)值仿真,仿真結(jié)果驗(yàn)證了所設(shè)計(jì)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.
