This paper investigates the implementation of output-delayed feedback control (ODFC) technique for controlling the sway angle of single pendulum gantry crane (SPGC) system. Linearized mathematical model of the SPGC in state space form is considered for the investigation. The designed ODFC has undergone complete stability analysis for a given controller gain.
In this paper, a new and improved stability condition is proposed for Takagi-Sugeno (T-S) fuzzy systems subject to interval time varying delay. The stability analysis is carried out by constructing a new Lyapunov-Krasovskii (L-K) functional along with the use of tighter bounding integral inequality to approximate the integral term coming out from the(More)
This paper presents a new & improved stability analysis for Takagi-Sugeno (T-S) Fuzzy system subjected to interval time-varying delay. The stability analysis provides a sufficient stability condition in an Linear Matrix Inequality (LMI) frame work that can estimate less conservative delay upper bound for a given lower bound of delay. The analysis is(More)
This paper presents a new approach to determine the optimal proportional-integral-derivative controller parameters for the speed control of a separately excited DC motor using firefly optimization technique. Firefly algorithm is one of the recent evolutionary methods which are inspired by the Firefly’s behavior in nature. The firefly optimization technique(More)
A robust H<inf>&#x221E;</inf> controller design in an LMI framework has been carried out for a load-frequency control problem of a single-area uncertain power system model. For carrying out this design, the uncertainties have been restructured by considering norm-bounded uncertainty instead of rank-1 uncertainty structure of [16]. The proposed design is(More)
This paper presents improved robust delay-range-dependent stability analysis of an uncertain linear time-delay system following two different existing approaches - (i) non-delay partitioning (NDP) and (ii) delay partitioning (DP). The derived criterion (for both the approaches) proposes judicious use of integral inequality to approximate the uncertain(More)
