A new approach of designing a robust controller for fuzzy parametric uncertain systems is proposed. A linear time invariant (LTI) system with fuzzy coefficients is called as fuzzy parametric uncertain system (FPUS). The proposed method envisages conversion of the FPUS into an uncertain (interval) state space controllable canonical form system in terms of(More)
In this paper, a discrete time sliding mode controller (DSMC) is proposed for higher order plus delay time (HOPDT) processes. A sliding mode surface is selected as a function of system states and error and the tuning parameters of sliding mode controller are determined using dominant pole placement strategy. The condition for the existence of stable sliding(More)
In this paper, a two-degrees-of-freedom control design methodology for interval plants to guarantee both the robust stability and performance has been considered. A simple necessary condition and sufficient condition for robust Hurwitz stability of interval polynomial has been obtained using the results of Nie [Nie YY. A new class of criterion for the(More)
In this paper, we propose a necessary condition and su±cient condition for interval polynomials using the results of Nie [13] for ¯xed polynomials. we Abstract also consider linear interval plant family in which the uncertainty in the plant is manifested via a pri-A simple necessary condition and su±cient condi-ori interval bounds for each numerator and(More)
A robust control strategy for design of robust model following sliding mode load frequency controller for single area power system based on uncertainty and disturbance estimator (UDE) has been presented where simple first order lowpass filter is used. The control strategy for elimination of reaching phase uses Ackermann’s formula and UDE for the estimation(More)
Research into the problem of classification of sonar signals has been taken up as a challenging task for the neural networks. Our purpose is to make a comparison of decision tree induction and neural network classifiers in a classification of sonar signal databases. The task is to discriminate between sonar signals bounced off a metal cylinder and those(More)
In this paper, a decentralized PI/PID controller design method based on gain and phase margin specifications for two-input-two-output (TITO) interactive processes is proposed. The decouplers are designed for systems to minimize the interaction between the loops, and the first order plus dead time (FOPDT) model is achieved for each decoupled subsystem based(More)
This paper presents design of PID controller using Characteristic Ratio Assignment (CRA) method. The design methodology uses reduced first order plus delay time (FOPDT) model of system. Based on required overshoot and settling time the controller parameters are computed using CRA method. To demonstrate the performance and stability of controller simulation(More)
In this paper, a design method for a robust PI/PID controller for fuzzy parametric uncertain systems is proposed. An uncertain Linear Time Invariant (LTI) system with fuzzy coefficients is referred as fuzzy parametric uncertain system. The fuzzy coefficients are approximated by intervals (crisp sets) using the nearest interval approximation approach to(More)
