Abstract

In this paper, the cascade control of the supply system for the heat exchanger is presented. The aim of the work is the construction of cascade control system, when the output for the inner loop is not measurable. This signal is reconstructed by using the state observer derived from the distributed parameter model of the heat transportation and its implementation is based on the orthogonal collocation method. The idea is verified by simulation and the results are compared with single loop control system with PI controller.
