Název v původním jazyce

Controller design and tuning of a delayed heat exchanger plant in a robust sense

Popis výsledku v původním jazyce

This chapter is aimed at the possible use of well-established and simple algebraic and robust control techniques for a delayed plant with heat exchangers, the modeling and identification of which were presented in Chapter 2. The algebraic part of the controller design is based on a special ring of stable and proper quasipolynomial meromorphic functions. The control system includes the master and slave controllers—it is also called as the two-feedback-controllers control structure. This configuration brings more degrees of freedom compared to the simple negative feedback loop. The robustness is considered in the sense that the feedback control system is stable and its performance is sufficient under some plant model perturbations and uncertainties. These fluctuations are mainly due to measurement imperfections, varying operational conditions and nonconstant ambient temperature during the year. Roughly speaking, the designed control law is less sensitive to variations of model parameters, which makes it more applicable in practice. Acceptable ranges of controller parameters’ values are then determined such that robust stability and performance are satisfied. Within these ranges, a multiobjective optimization technique is proposed to get eventual values. In addition, an idea how to approximate the designed infinite-dimensional controller with a finite-dimensional one is also given to the reader due to its better applicability. Finally, the reader is acquainted with simulation and experimental verification and comparison of the presented results
