This paper proposes a robust gain-scheduled H1 controller for lateral stability control of four-wheelindependent-drive electric vehicles via linear parameter-varying technique. The controller aims at tracking the desired yaw rate and vehicle sideslip angle by controlling the external yaw moment. In the design of controller, uncertain factors such as vehicle mass and tire cornering stiffness in ...

An integrated design of robust controller and fault estimator for linear parameter varying systems is presented in this paper. Based on gain-scheduled H∞ design strategy and scaled bounded real lemma, a linear parameter varying controller is developed, which can generate both control signals and fault estimates. To demonstrate the effectiveness of the proposed method, an uncertain system with a...

Reliable and eecient techniques are now available to synthesize gain-scheduled controllers. Such techniques take advantage of Linear Matrix Inequality (LMI) characterizations of gain-scheduled controllers and provide a global and systematic treatment of the gain-scheduling problem. This paper examines how such controller structures, designed in continuous time, can be discretized and implemente...

This paper deals with bumpless transfer between a number of observer-based controllers in a gain scheduling architecture. Linear observer-based controllers are designed for a number of linear approximations of a nonlinear system in a set of operating points, and gain scheduling control can subsequently be achieved by interpolating between each controller. The Youla-Jabr-Bongiorno-Kucera (YJBK) ...

ABSTRACT This paper investigates the dynamics of the SMART rotor, and presents a method to design a gain-scheduled controller to reduce the harmonic vibration throughout the flight envelope. The dynamics of the SMART rotor was examined at various flight conditions through nonli...

The work has done in this paper concern the passive fault tolerant control. Based on Gain-Adaptive Proportional-Integral-Derivative (PID) using the approach from the theory of Lyapunov and their application to the model vertical flying drone Quadrotor type, the PID controller with fixed parameters may fail to provide acceptable control performance. To improve the PID control effect, new designs...

In control theory, a controller parameter-tuning method called virtual reference feedback tuning (VRFT) is proposed. VRFT can tune using single experimental data. If be applied to vehicle, the yaw-rate adequately tuned without need for vehicle model. Therefore, this study expands results of realize desired autonomous vehicles. The key point proposed auto-tuning gain-schedule proportional–integr...

The article focuses on the issues of Load Frequency Control (LFC) under non-linear strategies in multi source multi area hydro thermal system. On practical perspective dead band, boiler dynamics, reheat steam turbine along with hydro turbine operating under two different area capacities are considered in the system. When subjected to random load variations in both the areas, the system exhibits...
