Autoresonant excitation and control of nonlinear mode for ultrasonically assisted drilling

The application of high-frequency vibration processes for intensification of machining requires a control technique for identification, excitation and stabilisation of the nonlinear resonant mode in machining systems with unpredictable variation of processing loads. Such a technique was developed with the use of a self-exciting mechatronic system. This method of control is known as autoresonance. Autoresonant control of ultrasonically assisted drilling machine intended to improve machining process is thoroughly analysed and the simulation results of analysis for both mechanical feedback and electrical feedback are presented together with the application of different filters
