In the study presented in this paper , the problem of the design and implementation of a two-axis sun tracking system was addressed by applying a set of two robotic systems, one for the automatic orientation of the photovoltaic modules and the second for providing the reference trajectory (robotic sensor). The design methodology was based on mechatronic concepts, in particular the VDI 2206 standard,...
In this article, the problem of parameter identification and state estimation for synchronous motors is tackled by means of the combination of algebraic techniques, in the context of a step by step approach. The step by step procedure consists in separating the estimation problem in three subsequent steps, in such a manner that it is possible to carry out each identification (estimation) step. The...
Active Disturbance Rejection (ADR) is a robust control paradigm which transforms the problem of controlling nonlinear systems by means of a direct active estimation. This estimation is further used to cancel the additive disturbances. This control design can be attained for some specific class of systems. Among others, if the system to be controlled is input-output linearizable (IOL), the tracking...
