WebOct 13, 2024 · Classical control algorithms for fixed-base robots and their extensions to free-floating robots require access to joint velocity measurements. Traditionally, joint positions q J can be directly measured with joint encoders from which joint velocities $\dot q_J$ and accelerations $\ddot q_J$ are computed via numerical differentiation. WebActuator failure and joint flexibility will dramatically impact space robot system control. In this paper, free-floating flexible-joint space-manipulator dynamic-modeling is studied and a state-observer-based robust backstepping fault-tolerant control is proposed for the system joint actuator failure. Based on the flexible-joint simplified model, the system’s … fighter aeroplane
