This paper deals with piecewise affine (PWA) approximation of nonlinear systems. Its motivation is simple. If the controlled plant exhibits nonlinear behavior, linear controller based on linearized model may often be unable to achieve satisfactory performance. On the other hand, intrinsic complexity of the nonlinear controller based on full nonlinear model(More)
This paper presents a case study of nonlinear model predictive control (NMPC) applied to a benchmark nonlinear boiler model. The motivation for NMPC is that if the controlled plant exhibits nonlinear behavior, a linear controller based on a linearized model may often be unable to achieve satisfactory performance. The case study in this paper, a power plant(More)
Solid oxide fuel cells (SOFC) can be used for both distributed electricity generation and cogeneration purposes. They have higher efficiency and certain other advantages over proton exchange membrane fuel cells. However an important weak point of SOFC cells is their lifetime and durability. In particular, high temperature and fuel utilization variations(More)
