Hardware-in-the-loop simulation of flight mach fuzzy controller

An efficient and reliable flight Mach controller is specially needed for an aircraft. A Flight mach fuzzy controller based on modern fuzzy control theory is designed for an unmanned aerial vehicle (UAV) using a turbojet engine. The theory and process of designing control law are introduced and its control performance is optimized by changing the scale factors. In order to evaluate the control performance, a mathematical simulation system and a hardware-in-the-loop (HIL) simulation platform are built. The mathematical simulation and HIL simulation are carried out respectively, and the simulation results are compared. The evaluation shows good control performance to stabilize the UAV flight Mach number to the target one quickly by controlling the engine work condition.
