Stochastic Model Predictive Control with Enlarged Domain of Attraction for Offset-Free Tracking

2018 Annual American Control Conference (ACC), 2018
The domain of attraction is central to stability and recursive feasibility of model predictive control (MPC). For stochastic linear systems, this paper addresses the problem of enlarging the domain of attraction of stochastic MPC (SMPC) for offset-free tracking. The proposed SMPC strategy relies on using an artificial steady-state target to enlarge the

A comparative study of state-space controllers with offset-free reference tracking

2015 20th International Conference on Process Control (PC), 2015
Steady-state control error occurs in case of unmeasured disturbances or disagreement between the model and the actual behaviour of the system because, state-space controllers do not have integral character. This problem (offset-free reference tracking) of state-space controllers has been observed in both theoretical and application areas (industrial ...

Nonlinear Adaptive Model Predictive Control of Constrained Systems with Offset‐Free Tracking Behavior

Asian Journal of Control, 2017
AbstractIn this paper, a nonlinear model‐based predictive control strategy for constrained systems based on an adaptive neural network (NN) predictor is proposed. The proposed controller is robust against the model uncertainties and external bounded disturbances.

Offset-Free Tracking of Model Predictive Control with Model Mismatch:  Experimental Results

Industrial & Engineering Chemistry Research, 2005
In this paper, a laboratory experiment has been used to investigate some aspects related to integral action in model predictive control (MPC). Simulations using the same model as that used for control design may indicate that integral action is present and that disturbances are handled well with no steady-state offset, but in practice, unmodeled ...

A 0.0056-mm² −249-dB-FoM All-Digital MDLL Using a Block-Sharing Offset-Free Frequency-Tracking Loop and Dual Multiplexed-Ring VCOs

IEEE Journal of Solid-State Circuits, 2019
This paper describes an ultra-compact all-digital multiplying delay-locked loop (MDLL) featuring a low-power block-sharing offset-free frequency-tracking loop (FTL) to calibrate the process–voltage–temperature variations of the voltage-controlled oscillator (VCO) frequency.

Offset-free Tracking: There and Back Again

2017
Feedback is necessary to reduce the effect of disturbances and to cope with unavoidable modeling errors. Nonetheless, the way in which feedback is used to achieve offset-free tracking in the presence of persistent errors or non-zero mean disturbances appears to be often a question of personal preference among possible different, sometimes ad-hoc ...
