Abstract
This study presents a novel approach to reduce pressure ripples in electric power (EP) steering systems by proposing a quantized sampled-data controller (QSDC) based on the Takagi-Sugeno (T-S) fuzzy-model approach for finite-time extended dissipative analysis. With special consideration of the influence of velocity on EP steering control, a fuzzy QSDC is designed to actively mitigate the pressure ripple effects. By developing a novel Lyapunov-Krasovskii functional (LKF) that fully incorporates the characteristics of the sampled-data and utilizes integral inequalities, the study determines the extended dissipative performance in finite time for a certain class of EP systems with the QSDC. Utilizing the LKF, the study derives a stability criterion expressed in linear matrix inequalities using the MATLAB toolbox. Finally, simulation studies are performed to illustrate the efficacy and improved performance of the proposed methodology.
This paper proposes an integrated fuzzy control and energy management strategy for nonlinear wind energy systems by combining the generalized Kalman–Yakubovich–Popov (gKYP) lemma with Takagi–Sugeno (T–S) fuzzy modeling. The nonlinear dynamics of the wind turbine are represented by a T–S fuzzy model, which enables the d...

To fulfill the dynamic and steady-state performance requirements of permanent magnet synchronous motors (PMSMs) in speed regulation, a practical prescribed-time fuzzy adaptive control approach is investigated. First, a novel continuously differentiable time-varying scaling function is constructed, which avoids the prob...

This paper addresses the design of an aperiodic sampled-data controller for Takagi-Sugeno (T-S) fuzzy systems. To achieve a larger maximum allowable transfer interval (MATI) between consecutive sampling instants, less conservative stability conditions are derived by constructing an improved Lyapunov functional. The pro...

This paper proposes a discrete-time sliding mode controller for a class of disturbed linear systems and investigates its dynamic characteristics. First, a novel discrete-time sliding mode reaching law is developed by redefining the variation rate of disturbances through a difference function. A disturbance estimation m...

: An Interval Type-2 (IT2) Fuzzy Controller (FC) design approach and a Linear Matrix Inequality (LMI)- based computational analysis method are proposed in this paper for Uncertain Stochastic Nonlinear Systems (USNSs) subject to deception attacks. For USNSs, the IT2 Takagi-Sugeno Fuzzy Model (TSFM) is constructed to cha...
