Overparameterised controllers can reduce non-singular costs
By means of two examples we show that non-singular costs can been reduced for adaptive controllers by overparameterising the estimators. The examples are for scalar and second order systems respectively. In the second example the tuning function design and the overparameterised adaptive backstepping design are compared. In both cases a system is constructed for which the overparameterised design is superior w.r.t. a non-singular measure of transient performance
Main goals and obtained results of the THERMINIC Project
International audienceTherminic (Thermal Investigation of ICs) is a Copernicus project, supported by the EU for the 1995-98 period. The main goals of the project are: development of innovative temperature sensors, checking the feasibility of on-line thermal monitoring, comparison of the temperature-field measurement and simulation methods of ICs, thermal model identification of the packages based on the measuring of thermal transients. The paper presents the achieved results at the two-thirds time of the project
