Optimizing Cascaded Control of Mechatronic Systems through Constrained Residual Reinforcement Learning

open access: yesMachines, 2023
Cascaded control structures are prevalent in industrial systems with many disturbances to obtain stable control but are cumbersome and challenging to tune.

Overlapping guaranteed cost control for uncertain continuous-time delayed systems [PDF]

open access: yes, 2005
Overlapping guaranteed cost control design problem is solved for a class of linear continuous-time uncertain systems with state as well as control delays. Unknown arbitrarily time-varying uncertainties with known bounds are considered.

Switching Control for Parameter Identifiability of Uncertain Systems

open access: yes, 2015
This paper considers the problem of identifying the parameters of an uncertain linear system by means of feedback control. The problem is approached by considering time-varying controllers.

Global Stabilization of Triangular Systems with Time-Delayed Dynamic Input Perturbations

open access: yes, 2018
A control design approach is developed for a general class of uncertain strict-feedback-like nonlinear systems with dynamic uncertain input nonlinearities with time delays. The system structure considered in this paper includes a nominal uncertain strict-

PDF-based tuning of stochastic optimal controller design for cyber-physical systems with uncertain delay dynamics

open access: yesIET Cyber-Physical Systems, 2017
Uncertain dynamics in communication network, including random delays and packet losses make it difficult to guarantee stability of cyber-physical systems (CPSs).
