Abstract: Traditional three-dimensional fuzzy controller for over more fuzzy rules is difficultly designed and used, a mixed controller combined Fuzzy control with PID control is proposed in this paper. This strategy uses three one-dimensional fuzzy controllers respectively being deviation, deviation change and deviation's deviation change by weighting fusion for forming the M-type controller. It solves the problem of multivariable fuzzy control rules more increasing. Simultaneously by use of integral to deviation, M-type controller can eliminate steady difference of system and improve system's steady precision. Moreover, parameter setting method of M-type controller is introduced and its stability is analyzed. Simulation results show that M-type controller performs better than two-dimensional fuzzy control and PID control in dynamic and static performance.
