A unique and useful dynamic control system has been invented for the control of a catalytic combustion system for use on a dynamic plant, preferably, a gas turbine engine. The dynamic control system facilitates the replacement of conventional flame combustion systems with catalytic combustion systems, which produce far less pollutants, by producing acceptable transient performance of the combustion system. A method of controlling the catalytic combustion process comprises the steps of calculating a mass flow of air introduced into the combustor, monitoring a flow of fuel to be combusted within the combustor, monitoring a temperature of the air introduced into the combustor, calculating an inlet temperature set point based on the mass flow and fuel flow, and controlling a pre-burner to heat the air based on the inlet temperature set point, the mass flow, and the temperature of the air. Further, the mass flow may be estimated based on ambient air temperature and pressure, and compressor speed. A catalytic combustion gas turbine system is also presented, the operation of which is controlled by a dynamic plant controller which generates a fuel flow rate demand signal to control the flow of fuel to be combusted in response to dynamic plant demands.
