A Takagi-Sugeno-Kang (TSK) fuzzy controller design for a PWM boost DC-DC switching regulator operating at different steady-state voltages is presented. On the other hand, the controller assigns different linear control laws according to the steady-state voltage value and limits their application to the small-signal perturbations. On the other hand the controller assures a proper start-up to reach the desired steady-state voltage by means of properly saturating the PWM according to the sliding-mode control principles. As a result, both equalized small-signal behaviour and a controlled start-up are achieved for different steady-state voltages, thus enhancing the regulator features. Simulation results for a current-controlled boost regulator operating at different steady-state voltages are presented to validate the approach.
