...Min Wan; Mou Chen; Mihai Lungu Purpose This paper aims to study a neural network-based fault-tolerant controller to improve the tracking control performance of an unmanned autonomous helicopter with system uncertainty, external disturbances and sensor faults, using the prescribed performance...

... is reset to a preset condition when the controlled variable crosses zero. The mathematical analysis also shows the system trajectory can converge to a set centered at the origin. In this paper, we design a reset and prescribed performance control policy that is robust against system uncertainty...
