Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …
