The vast majority of control loops in industrial production plants use the classic Proportional Integral Derivative (PID) control, which cannot necessarily guarantee an adequate behavior due to the complexity of the models that govern these processes. The great use of PID control is mainly for its simplicity and ease of implementation. In this work, a methodology is proposed to approach industrial process plant models with the fuzzy Takagi-Sugeno (TS) control. To achieve zero error in steady state output variables, a new state is added to the system through an integral action. To speed up the system response an assignment of specific decay rates for each state variable is considered. To solve the problem that in practical applications, some or all of the state variables cannot be measurable, a fuzzy TS state observer is considered. The design of the controller and observer gains were obtained applying the separation principle and based on Lyapunov's theory using Linear Matrix Inequalities (LMIs). The proposed methodology is applied to a thermal steam plant for electrical generation and in the simulation verifies the adequate behavior of the system for a wide operating range.
