Observer-based bilinear control of first-order hyperbolic PDEs: Application to the solar collector

Sarah Mechhoud, Taous-Meriem Laleg-Kirati
2015 2015 54th IEEE Conference on Decision and Control (CDC)  
In this paper, we investigate the problem of bilinear control of a solar collector plant using the available boundary and solar irradiance measurements.  ...  By combining a boundary state observer and an internal energy-based control law, a nonlinear observer based feedback controller is proposed.  ...  Using the internal energy a distributed stable and robust control law relying on feedback from the distributed collector fields internal energy was introduced.  ...
