For an air-breathing hypersonic vehicle model subject to input constraints, this paper is concerned with the application of linear control theory to design its flight control system. In the framework of integral quadratic constraints (IQCs), the standard linear parameter-varying (LPV) control method is generalized to deal with the parametric, dynamic uncertainties and saturation nonlinearities associated...
This paper presents an active queue management (AQM) scheme based on sliding mode control (SMC) in order to solve the problem of congestion control in TCP communication. First, sliding mode observer is designed for input delay network system, a sufficient condition is given for the existence of such an observer in terms of linear matrix inequality (LMI). Then, based on estimated system state, a controller...
We propose an underactuated mechanical system named inverted pendulum on a cart beam system. The proposed system has three degrees-of-freedom and one control input. The mathematical model is derived using Lagrangian method and the stabilization is achieved with constraints using a linear controller designed based on linear matrix inequality approach. Simulation results are presented to validate the...
A novel control strategy based on passivity theory was proposed with special attention to trajectory tracking and robust control of rigid robot. In this paper, robot model was divided into nominal model and uncertainty part. Based on the backstepping approach, feedback passivity was used to design controller for the nominal model. A variable structure concentrated compensation controller was adopted...
