摘要: Abstract In this brief, a switching fault-tolerant control (FTC) scheme is presented for moving vehicle-mounted flexible manipulator subject to state constraints. The dynamic characteristics of the system are represented by coupled ordinary differential equations and partial (ODEs–PDEs). When actuators healthy, vibration position regulations can be realized without violation given constraints based on Barrier Lyapunov Function (BLF). Moreover, strategy introduced prevent transgression even under actuator failure detecting faults as-assisted proposed monitoring functions. closed-loop states kept within bounds FTC laws. By extending LaSalle's Invariance Principle an infinite dimension, asymptotic stability fault-free strictly verified. Simulation results demonstrate effectiveness approach.
