This letter addresses the problem of emulation-based dynamic output-feedback control for discrete-time linear parameter varying systems under actuator saturation. Sufficient conditions based on matrix inequalities (LMI) are derived to design parameters two dependent event-triggering rules handling sensor-to-controller and controller-to-actuator communication guarantee regional asymptotic stabil...

Omar Farhan Aljanaideh Concordia University, 2013 Smart material actuators are increasingly being explored for various micropositioning applications. Magnetostrictive actuators, in particular, are considered attractive for micro/nano positioning and high speed precision machining due to their high energy density, resolution and force capacity. The magnetostrictive actuators, similar to other sm...

This paper investigates the problem of output feedback attitude control for rigid spacecraft subject to inertia matrix uncertainty, space disturbance, and input saturation. Firstly, a model transformation is adopted convert an system with immeasurable angular velocity into new system. All states converted are measurable available feedback; however, contains mismatched uncertainty resulting from...

This paper addresses a semi-active suspension control of the full vehicle equipped with 4 controlled semi-active dampers by using a full 7 degree of freedom (DOF) vertical model. First, the dissipativity conditions of the semi-active dampers are recast as saturation conditions on the control inputs. Then, the suspension controller is derived by solving a state feedback control design problem fo...

Thispaper presents a new nonlinear controller design method for regional pole placement of uncertain discretetime systems. The constraint of control input saturation is considered in the design. A sufficient condition is derived for the robust stabilization and the desireddynamic performance represented by the settling time and damping ratio.The design is formulated in terms of linear matrix in...

A Robust Anti-Windup Control (RAWC) method is proposed for n-Degree-of-Freedom (DOF) electrically driven robots considering the actuator voltage saturation. The actuator’s saturation is fairly modeled by a smooth nonlinear function and the control design task is developed to avoid windup besides being robust against both model uncertainties and external disturbances. As a major point, the paper...
