Comparison of Controller Designs for a Stirling Co-generator
IFAC Conference CAO’06 – April 26-28. 2006 Paris, France
The Stirling co-generator studied in this paper is motorized by a free-piston Stirling engine. Its piston, which has an alternative linear motion, is the secondary (i.e. rotor) of a linear induction generator. The system is submitted to parameter uncertainties and sensor noise. This paper considers a comparison of two different controllers. One is designed using a pole placement methodology; the other involves H∞ techniques using coprime factors. The comparison examines both performance and stability robustness.
