Aiming at the low precision of the traditional fuzzy PID controller for AGV path tracking
a fuzzy PID method of deviation rectification control based on proportional adjustment and integral separation is proposed.Firstly
the kinematics model for AGV is analyzed and established. Secondly
input and output membership function and fuzzy control rules of the fuzzy PID controller is designed. Finally
the proportion term and integral term of fuzzy controller output make the proportion adjustment and integral separation operation based on the magnitude of the deviation. Simulation experiments show that the integral separation can effectively reduce the system overshoot and the proportional adjustment can accelerate the response speed of the system. The designed deviation rectification controller has the advantages of rapidity and stability.
