Adaptive Algorithms for Control of Combustion
Abstract
Rather than investigate a particular combustor, a whole class of combustion systems, susceptible to damage from combustion instabilities, is considered Under some simple and realistic assumptions (pressure waves reflected from the combustor boundaries smaller than incoming waves, flame stable in itself, limited bandwith flame response), it is demonstrated that a finite dimensional approximation to the open-loop transfer function of such a combustion system satisfies some general properties (stable zeros, small relative degree) that are exploited to design adaptive active controllers guaranteed to stabilise the self-excited combustion oscillations. In particular, for the practical case of a combustio system with time delay, a completely new and simple adaptive control design is presented and a formal proof for stability is given. The performance of such stable adaptive controllers is illustrated in a simulation.
