Guaranteed robustness properties of multivariable, nonlinear, stochastic optimal regulators [PDF]

open access: yes, 1983
The robustness of optimal regulators for nonlinear, deterministic and stochastic, multi-input dynamical systems is studied under the assumption that all state variables can be measured.

High-order volterra model predictive control and its application to a nonlinear polymerisation process [PDF]

open access: yes, 2005
Model Predictive Control (MPC) has recently found wide acceptance in the process industry, but the existing design and implementation methods are restricted to linear process models. A chemical process involves, however, severe nonlinearity which cannot

Hard constraints in control state variables of multivariable nonlinear processes resolved by elementary nonlinear decoupling [PDF]

open access: yesModeling, Identification and Control, 1998
A model based control strategy for nonlinear multivariable processes having hard constraints on both control and state variables, is derived based upon the concept of Elementary Nonlinear Decoupling (END). In END a property space is defined which has the

Stability of quantized time-delay nonlinear systems: A Lyapunov-Krasowskii-functional approach [PDF]

open access: yes, 2009
Lyapunov-Krasowskii functionals are used to design quantized control laws for nonlinear continuous-time systems in the presence of constant delays in the input. The quantized control law is implemented via hysteresis to prevent chattering.

Sparse identification of nonlinear dynamics for model predictive control in the low-data limit [PDF]

open access: yesProceedings of the Royal Society A, 2017
Data-driven discovery of dynamics via machine learning is pushing the frontiers of modelling and control efforts, providing a tremendous opportunity to extend the reach of model predictive control (MPC). However, many leading methods in machine learning,

Controller performance design and assessment using nonlinear generalized minimum variance benchmark : scalar case [PDF]

open access: yes, 2004
A nonlinear version of the Generalized Minimum Variance (GMV) multivariable control law has been recently derived for the control of nonlinear, possibly time-varying systems.
