A general photo-electro-thermo-temporal theory for light-emitting diode (LED) systems
, 2010 IEEE Energy Conversion Congress and Exposition, ECCE 2010 - Proceedings, Pages: 184-191This paper presents a dynamic photo-electro-thermal theory for LED systems. In addition to photometric, electrical and thermal aspects, this theory incorporates the time domain into the generalized equations. A dynamic model for a general LED system is developed for system analysis. This theory highlights the fact that the luminous output of an LED system will decrease with time from the initial operation to the steady-state due to the rising temperature of the heatsink and the LED devices. The essential thermal time constants involved in the LED systems are explained. The time factor is critical in understanding how much the luminous output will decrease with time and is essential to the optimal designs of LED systems that are operated continuously (e.g general lighting) or momentarily (e.g. traffic lights). Experiments on several LED systems at different time frames have been conducted and the practical measurements confirm the validity of this theory. © 2010 IEEE.

Receding Horizon cost optimization and control for nonlinear plants
, IFAC Proceedings Volumes (IFAC-PapersOnline), Vol: 43, Pages: 1217-1223, ISSN: 1474-6670Control performance and cost optimization can be conflicting goals in the management of industrial processes. Even when optimal or optimization-based control synthesis tools are applied, the economic cost associated with plant operation is often only optimized according to static criteria that pick, among all feasible equilibria, those associated to minimal cost. This note collects and illustrates some recent advances in Receding Horizon optimization of nonlinear systems that allow to simultaneously optimize transient and steady-state economic performance. © 2010 IFAC.

A Fast Well-conditioned Interior Point Method for Predictive Control
, IEEE Control and Decision ConferenceInterior point methods (IPMs) have proven to be an efficient way of solving quadratic programming problems in predictive control. A linear system of equations needs to be solved in each iteration of an IPM. The ill-conditioning of this linear system in the later iterations of the IPM prevents the use of an iterative method in solving the linear system due to a very slow rate of convergence; in some cases the solution never reaches the desired accuracy. In this paper we propose the use of a well-conditioned, approximate linear system, which increases the rate of convergence of the iterative method. The computational advantage is obtained by the use of an inexact Newton method along with the use of novel preconditioners. Numerical results indicate that the computational complexity of our proposed method scales quadratically with the number of states and linearly with the horizon length.
