  • In this paper, a novel hybrid fuzzification method combining conventionally used triangle Membership functions (MFs) with two new membership functions - a peaky-triangle MF and a round-triangle MF - is proposed to improve the control effect of trajectory tracking control problems. Then its analog integrated circuit is designed and fabricated using a 0.6μm CMOS technology for hardware implementation. The experimental results show that this circuit provides an accurate output compared to the theoretical one with a fuzzification speed of 6.67MHz, which is fast enough for real-time applications. This special hybrid fuzzification can help improving the performance of fuzzy logic controller without increasing complexity.
