Robust mixed order backstepping control of non-linear systems
(Institution of Engineering and Technology, 2018-06-12)
Robust backstepping control of non-linear systems with derivation orders (commensurate or non-commensurate) lying at interval (0, 2) is proposed in this study. The stability and robustness properties are proved using a ...
A note on a system with radiation boundary conditions with non-symmetric linearisation
(Springer Wien, 2018-08)
We prove the existence of multiple solutions for a second order ODE system under radiation boundary conditions. The proof is based on the degree computation of I- K, where K is an appropriate fixed point operator. Under a ...
Optimisation-based Switch Allocation To Improve Energy Losses And Service Restoration In Radial Electrical Distribution Systems

Robust STATCOM control for the stabilisation of fixed-speed wind turbines during low voltages
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
This paper presents a robust voltage control scheme for fixed-speed wind generators using a static synchronous compensator (STATCOM) controller. To enable a linear and robust control framework with structured uncertainty, ...
Energy optimal control of thermal comfort in trams
(Elsevier Ltd, 2018)
This paper presents a method for thermal comfort control for trams which achieves the desired thermal comfort and minimises the power consumption of heating,ventilation and air conditioning (HVAC). Mathematical models of ...
Growth and green income: evidence from mining in Chile
This paper estimates the true economic income for the Chilean mining sector, using the welfare foundations for the usual net domestic product (NDP) income measure of the traditional National Accounts System (NAS) provided ...
Stochastic assessment of distributed generation hosting capacity and energy efficiency in active distribution networks
Active network management (ANM) aims to increase the capacity of variable distributed generation (DG), which can be connected to existing distribution networks. In this study, it is proposed to simultaneously consider the ...
An augmented Lagrangian technique combined with a mortar algorithm for modelling mechanical contact problems
A finite element formulation for three dimensional (3D) contact mechanics using a mortar algorithm combined with a mixed penalty-duality formulation from an augmented Lagrangian approach is presented. In this method, no ...
Optimisation-based switch allocation to improve energy losses and service restoration in radial electrical distribution systems
This study presents a newmethodology for the optimal allocation of switching devices in radial electrical distribution systems (EDSs). A specialised greedy randomised adaptive search procedure (GRASP) algorithm defines the ...
