چکیده
A stochastic model predictive control framework over unreliable Bernoulli communication channels, in the presence of unbounded process noise and under bounded inputs, is presented for tracking a reference signal. The data losses channel are compensated by carefully designed transmission protocol, those sensor dropout compensator. class saturated, disturbance feedback policies proposed noisy compensation. governor employed to generate trackable trajectories stability constraints ensure mean-square boundedness error. overall approach yields computationally tractable quadratic program, which can be iteratively solved online.

Model Predictive Control over Unreliable Communication Links
In this paper an issue of data dropout in networked control systems is solved. The model predictive control approach is used where the future control inputs up to a given horizon are evaluated at each sampling instant. In case the current output value is lost and the control input can not be computed, the future control input calculated at previous sampling instant can be used instead. The prop...
متن کاملOn Stochastic Model Predictive Control with Bounded Control Inputs
This paper is concerned with the problem of Model Predictive Control and Rolling Horizon Control of discrete-time systems subject to possibly unbounded random noise inputs, while satisfying hard bounds on the control inputs. We use a nonlinear feedback policy with respect to noise measurements and show that the resulting mathematical program has a tractable convex solution in both cases. Moreov...
متن کاملMinimax control over unreliable communication channels
In this paper, we consider a minimax control problem for linear time-invariant (LTI) systems over unreliable communication channels. This can be viewed as an extension of the H optimal control problem, where the transmission from the plant output sensors to the controller, and from the controller to the plant are over sporadically failing channels. We consider two different scenarios for unreli...
متن کاملStochastic Model Predictive Control
Model Predictive Control (MPC) is a control strategy that has been used successfully in numerous and diverse application areas. The aim of the present article is to discuss how the basic ideas of MPC can be extended to problems involving random model uncertainty with known probability distribution. We discuss cost indices, constraints, closed loop properties and implementation issues.
متن کاملOffset-free reference tracking with model predictive control
The standard way to achieve offset-free tracking in MPC is to add the disturbance dynamics to the prediction model and then use an observer to estimate the real disturbance. Existing algorithms only consider piecewise constant signals, while in practice it is often desirable to have a wider choice of reference and disturbance dynamics, such as sinusoids and ramps. This work provides a generaliz...
