چکیده
In this paper, a nonlinear predictive controller is proposed for variable-speed induction motor. The research work directed towards improving the trajectory tracking capability, stability guarantee, robustness to parameter variations, and disturbance rejection. Generalized Predictive Control (GPC) without constraint output-constrained motor drive illustrated. variables be controlled are rotor speed flux trajectory. load torque considered an unknown disturbance. Finally, tuning of GPC automatically determined. simulation results show good performance dynamic system.

End Point Constraints Nonlinear Continuous Predictive Control for Induction Motors
In this paper the optimal nonlinear predictive cascaded control structure is presented with application to induction motors, which provides global asymptotic tracking of smooth speed and flux trajectories. The controller is based on a finite horizon continuous time minimization of nonlinear predicted tracking errors. With full state measurement assumption, the robustness properties with respect...
متن کاملRobust sensorless predictive control of induction motors with sliding mode voltage model observer
In this paper, a robust sliding mode prediction model is combined with a sliding mode voltage model observer to achieve a sensorless predictive torque control method. In order to compensate the uncertainties of the stator and rotor resistances and the offset of measured current, sliding mode feedbacks were added to the voltage model observer. To reduce the effect of the errors that are injected...
متن کاملNonlinear model predictive control applied to vision-based spacecraft landing
Real-time optimal control has eluded practical implementation for most systems so far. The reason being mainly related to the scarce computational resources available and the high CPU requirements of commonly proposed real-time optimal control architectures. In this paper we show how, by a careful use of the Nonlinear Model Predictive Control approach one can obtain a real-time control system a...
متن کاملNonlinear Model Predictive Control applied to E. Coli Cultures
Abstract: This paper proposes a nonlinear model predictive control scheme with particular application to the regulation of acetate concentration in order to maximize the biomass growth during fed-batch cultures of E. Coli. A reference feed rate which enables to maintain the acetate concentration at a specified level is first determined by means of optimal conditions. This feed rate is further u...
متن کاملNonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot
This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...
