This paper presents a method for designing linear controllers to achieve robust tracking and disturbance rejection properties. Wide range of references and disturbances such as step and sinusoid forms are covered. The proposed control structure comprises a combination of state-feedback and output-feedback strategies. The output-feedback structure is selected based on the internal model principle and...
In this paper we present a systematic procedure to design robust fuzzy controller for exponentially stabilizing affine nonlinear systems, based on their TS fuzzy model. For robust design we consider modeling error in TS model and as well as perturbation in the original nonlinear system. Minimization of cost function along with mapping closed loop poles to desired poles are considered simultaneously...
This paper proposes an optimal control approach for the robust control design problem of the linear time-delay systems, which takes parameter uncertainties and state delay into account. It is shown that the robust control problem can be equivalently transformed into an optimal control problem with the amount of plant uncertainties indirectly reflected in the performance index. By introducing algebraic...
The robust control problem for linear systems with parameter uncertainties and time-varying delays is examined. By using an appropriate uncertainty description, a linear state-feedback control law is found, ensuring the closed-loop system's stability and a performance measure, in terms of the guaranteed cost. A linear matrix inequality objective minimization approach allows to determine the "optimal"...
