Abstract :
The mathematic models of components for hydraulic pump, brake valve, brake cylinder and so on are established for the hydraulic brake system based on the parameters of a certain unmanned aerial vehicle hydraulic system. According to brake built-in test scheme, the hydraulic brake system is designed and simulated. In order to improve the performance of system, the optimization algorithms of traditional PID and fuzzy adaptive PID are discussed by simulation experiment in Matlab/Simulink. The simulation results prove that the optimization arithmetic of built-in test for hydraulic brake is satisfied.
