As an important equipment for deep well hoisting, the safe and stable operation of the Blair mine hoist is vital for the development and utilization of deep mineral resources.However, it is always a challenging task to keep consistent wire rope tension in the event of an actuator VIBRATOR CLASSIC fault.In this study, an adaptive dynamic surface technology-based actuator fault-tolerant scheme is proposed.
A fault observer with a neural network adaptation term is designed to estimate the loss of actuator efficiency caused by faults.Considering the redundant characteristic of the two actuators, a novel dynamic surface technology-based controller with a fuzzy assignment and state constraints is developed to eliminate the impact of fault.The stability of the closed-loop system under the proposed strategy is theoretically proved by rigorous Lyapunov analysis.
Comparative experiments under various conditions are carried out on a xPC based mine hoist platform, and the results Nail Lacquer show the applicability together with the superiority of the proposed scheme.
