Relative Degrees and Output Tracking Control of T-S Fuzzy Systems

摘要：

　　This paper presents a new study on the relative degrees of T-S fuzzy systems:(x)(t)=(E)N i=1 μi(t)Aix(t)+(E)N i=1 μi(t)Biu(t),y(t)= (E)N i=1 μi(t)Cix(t),where(Ai,Bi,Ci)are some non-canonical form matrices,and proposes a feedback linearization based control design method for such systems.The study extends the system relative degree concepts,commonly used for control of complex nonlinear systems,to T-S fuzzy systems,and derives various relative degree conditions for general T-S fuzzy systems and establishes the relative degree dependent normal forms.A feedback linearization control design procedure is developed for such a system using its normal form,to achieve closed-loop stability and output tracking under relaxed design conditions.An illustrative example is presented with simulation results to show the control system design procedure and desired performance.
