A device is provided for regulating a combustion engine whose operation is governed by a set of parameters P.sub.i (1.ltoreq.i.ltoreq.n), including essentially an assembly of 'm' regulation loops for regulating 'm' parameters (with m.ltoreq.n), a set of 'q' sensors (with q=n-m) for measuring the parameters which are possibly not regulated and a regulator common to the assembly of these 'm' loops, for providing, from the different references and the values detected by the different sensors, a signal controlling the different actuators so as to ensure the evolution of each of the regulated parameters, in connection with the evolution of all or part of the other parameters, regulatable or not, regulated or not and for maintaining the engine at all times in a condition of optimum operation.

A spark ignition system for a gas turbine electronically controls the cycle of charge and discharge of a spark generator of the capacitive type. There is a function generator (5) which derives a reference voltage as a function of the speed of the turbine and possibly of other parameters. A charge control (6) for the capacitive cell (9) and a spark frequency control (7) are controlled by the reference voltage. Reignition in the case of flame extinction is controlled by an opto-electronic arrangement (11, 12, 13) which drives a reignition circuit (14), when flame extinction is detected. The reignition circuit produces a voltage which is superimposed on and over-rides the speed reference voltage to activate the system to produce ignition at a start condition. The system can be used for ignition of a gas turbine, especially a turbo-compressor.
