More than 40 years after fuzzy logic control appeared as an effective tool to deal with
complex processes, the research on fuzzy control systems has constantly evolved. Mamdani …

This paper reviews the stability analysis of continuous-time fuzzy-model-based (FMB)
control systems, with emphasis on state-feedback control techniques, which is an essential …

Classical Takagi–Sugeno (T–S) fuzzy models are formed by convex combinations of linear
consequent local models. Such fuzzy models can be obtained from nonlinear first-principle …

This paper presents the stability analysis of polynomial fuzzy-model-based (PFMB) control
systems using the sum-of-squares (SOS) approach. The PFMB control system under …

In 2015, we celebrate the 50th anniversary of Fuzzy Sets, ten years after the main
milestones regarding its applications in fuzzy control in their 40th birthday were reviewed in …

This paper presents stability analysis of polynomial fuzzy-model-based (FMB) control
systems using the sum-of-squares (SOS) approach. Recently, stability analysis of the …

To effectively suppress the horizontal vibration of a high-speed elevator car caused by
uncertainties such as the irregularity of guide rails and the piston wind in the hoistway, this …

This paper deals with stability analysis and control design problems for continuous-time
Takagi–Sugeno (T–S) fuzzy systems. The first aim is to present less conservative linear …

This paper proposes two improvements in the design of unknown input observers (UIO) for
linear parameter varying (LPV) systems. First, the parameter dependency of the UIO is not …

Improvements of recent stability conditions for continuous-time Takagi-Sugeno (TS) fuzzy
systems are proposed. The key idea is to bring together the so-called local transformations …
