Comparing Algebraic and Constrained Pole Assignment Controllers for a Thermal System

This paper compares two approaches to the control design for a thermal plant. This is dominant by two modes of the heat transfer - the fast mode (radiation) and the slow mode (conduction), by the nonlinear state dependent dynamics and by necessity to apply robust control design approaches. The algebraic and the constrained pole assignment controllers are compared both from the point of view of the nominal tuning required for achieving fastest possible monotonic transient responses and from the availability and easy of the controller robustification. The real experiment is used to verify the results.
