Mechatronics for noise control: on the capabilities of ENC

Evolvable noise controllers (ENCs) are mechatronics systems that are being designed for active noise suppression of non-periodic noises and vibrations in automotive, aeronautical and industrial applications. ENCs are special type of neuro controllers that have been repeatedly demonstrated to possess an excellent faculty for real world control applications. In this paper, ENC control devices are introduced and it will be demonstrated how they effectively suppress periodic and non-periodic noises. ENC control is applied for suppressing parasitic oscillations in a simulated turbine jet engine combustion chamber and will be compared against published traditional controllers for the same problem. The advantages of the ENC devices are discussed in detail and future implications are made
