This paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. The feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. Thus the computation of the flat output for reduced order model of the synchronous machine with simp...

This paper describes an integrated path planning and tracking control framework for autonomous verticaltake-off-and-landing (VTOL) vehicles, specially a quadrotor. The path planning adopts a receding horizon strategy to repeatedly plan a local trajectory that satisfies the vehicle dynamics and obstacle avoidance requirement. A tracking controller is then designed to track the optimised path. Th...

This paper presents a Delayed Generalized Predictive Controller (DGPC) by internal model for bilateral teleoperation systems in the presence of both communication delays and force feedback. First, the Π-freeness algebraic property of mechanical delayed systems, which presents some similarity with the notion of flatness, is used for the slave system to track a master system reference trajectory;...

This paper presents a sliding mode controller for a narrow tilting three wheeled vehicle. A dynamic model of eighteenth order is presented for simulation purposes only. Design and analysis are based on a simpler third order model of a bicycle. The validity of this simplification is verified through simulations. Because of the flatness of the bicycle, trajectories given by a presumed driver are ...

For a vehicle equipped with active single-wheel steering, brake, drive and suspension systems a nonlinear vehicle model is presented. On the basis of this model an integrated vehicle dynamics control is developed comprising all of the mentioned chassis actuators to control the plane vehicle motion. The basic control strategy consists in two parts. One part is a flatness based tracking controlle...

An Active Disturbance Rejection Control (ADRC) scheme is proposed for a trajectory tracking problem defined on a nonfeedback linearizable Furuta Pendulum example. A desired rest to rest angular position reference trajectory is to be tracked by the horizontal arm while the unactuated vertical pendulum arm stays around its unstable vertical position without falling down during the entire maneuver...

This paper deals with the tracking control design for systems governed by linear parabolic partial differential equations with spatially and temporally varying coefficients and boundary input. For the boundary feedback control the backstepping method is applied, which allows to determine an exponentially stabilizing state feedback controller such that the closed-loop system behaves in the nomin...

A model predictive control (MPC) scheme for a permanentmagnet synchronous motor (PMSM) is presented. The torque controller optimizes a quadratic cost consisting of control error and machine losses repeatedly, accounting the voltage and current limitations. The scheme extensively relies on optimization, to meet the runtime limitation, a suboptimal algorithm based on differential flatness, contin...

This paper presents a method for controller synthesis in the bond graph domain. A dynamic feedback linearization and decoupling controller of rotor speed and rotor-flux amplitude of a current-fed induction motor is derived on the basis of a flatness analysis entirely conducted on a two-input nonlinear bond graph model of the motor. Once the rotor speed has been found as the first flat output, a...

In this paper, output tracking control of a helicopter based unmanned aerial vehicle model is investigated. First, based on Newton-Euler equations, a dynamical model is derived by considering the helicopter as a rigid body upon which a set of forces and moments act. Second, we show that the model cannot be converted into a controllable linear system via exact state space linearization. In parti...
