| الوصف: | In this thesis, we study the design and the implementation of generic control algorithms for systems composed of distributed MEMS in a semi-centralized context, i.e., only the direct neighbours can communicate. The control is computed in real time by a network of independent microcontrollers, each of them being associated with a couple of sensors and actuators. So the challenge is to introduce the possibility of communications between neighbour microcontrollers in order toimplement control laws based on communications between neighbours. We focus on distributed control applications of the diffusive application where real-time implementations are an essential feature. To address this problem, the diffusive realization (DR) theory and its approximation are used. The advantage of DR is to deal with nonlocal problems encountered in many physical situations. Firstly, we recall the diffusive realization theory presented in the PhD thesis of Yakoubi [36]. However, his results were rather inaccurate. More precisely, the DR theory requires an analytic extension of the kernel p. This leads to non-uniformly bounded extensions with respect to the number of polynomials which causes high numerical errors. Therefore, in this thesis we apply an additional change of variables to the kernel p and its extension so that they become defined in an extension domain which eliminates an important source of error. The DR theory and its approximation are illustrated on a Lyapunov equation arising from the optimal control theory of the heat equation. Then we discuss expected gains if the method is implemented on different parallel computer topologies based on corresponding designed networks. The envisioned applications are for realtime distributed control on distributed computing architectures. Namely, we present results for three parallel topologies: line topology, hypercube topology, binary topology. We also compare the computation times between our algorithm with these topologies and a direct spectral method with a line topology. These ... |
