1 Abstract—Utilizing model reference adaptive control approach and multiple Lyapunov functions method, we propose a switched adaptive controller for uncertain switched linear systems in control canonical form. These systems exist naturally in many practical applications, such as variable capacity hydraulic pump involving discrete changes that are specified by the valve position. We show that th...

This study presents a control design of roll motion for vertical take-off and landing unmanned air vehicle (VTOL-UAV) based on the Model Reference Adaptive Control (MRAC) scheme in hovering flight phase. The adaptive laws are developed UAV system under nonparametric uncertainty (gust wind disturbance). Lyapunov-based stability analysis controlled has been conducted have accordingly developed. U...

In this paper, a new sensorless model reference adaptive method is used for direct control of active and reactive power of the doubly fed induction generator (DFIG). In order to estimate the rotor speed, a high frequency signal injection scheme is implemented. In this study, to improve the accuracy of speed estimation, two methods are suggested. First, the coefficients of proportional-integral ...
