On terrain following system with fuzzy-PID controller

By replacing terrain forward-looking radar with digital map, autonomous terrain following system remedies intrinsic defects of traditional terrain following system. Through analyzing the terrain following trajectory control system, introducing the normal acceleration signal, autonomous terrain following system constructs a kind of fuzzy PID controller, and designs an autonomous terrain following system based on the normal acceleration. The simulation results show that overload curve of the designed system meets the requirements, the system control precision is satisfying, and anti-jamming ability is improved to some extend, which verify the rationality and feasibility of the design.
