Abstract

The problem of designing a robust state feedback control that provides global stability for an uncertain nonlinear system has been the subject of considerable research over the last decade. To resolve these problems, a new design method of robust fuzzy control proposed in this paper. The solution offered is by creating multiple softswitching with Takagi-Sugeno fuzzy model for optimal solution control at all operating points that generate uncertainties. Optimal solution control at each operating point was designed using linear quadratic integral tracking problem optimal control. A case study of engine torque control of spark ignition engine is used to prove this method, since spark ignition engine is a non-linear system with wide uncertainty
