Abstract In order to carry out yawing control effectively, and enhance the stability and robust of yawing control system, the paper proposes a new method for yawing control system named Fuzzy-PID synthesis control. The control method mainly consisted of three parts: the Fuzzy control part of big error scope, the Fuzzy-I control part of small error scope, the Fuzzy-I-PD control part of micro error scope. Fuzzy-PID synthesis controller is designed according to the method, and yawing vector control system is built. Comparing the simulation curves with common PID control and fuzzy PID subsection control, the results indicate that the Fuzzy-PID synthesis control system has better performances in the stability and robust of yawing system, which increases the safety factor of system.
