JCIR_V4_N3_RP1 Fuzzy Modelling of Tunnel Diode Circuit Mohd Aqib Santosh Kumar Suman Journal on Circuits And Systems 2322–035X 4 3 1 5 T-S Fuzzy Model (Takagi Sugeno Fuzzy Model), Tunnel Diode, Parallel Distributed Compensation (PDC) This paper presents the T-S fuzzy model of the tunnel diode circuit which is one of the well-known benchmark in non-linear problem. The non-linear differential equation of tunnel diode is linearized with the help of T-S fuzzy model which consists of a number of linear sub-systems. At the end, it was observed that the over-all fuzzy system is unstable, so the fuzzy controller using Parallel Distributed Compensation (PDC) approach is employed for its stable working.
