An approach has been developed to design resonant vibratory equipment as self-sustained oscillating systems with electronic and electromechanical positive feedback and an actuator of a synchronous type. The feedback produces the exciting force by means of transformation and amplification of the motion signal. Autoresonant control relies entirely on the amplitude-phase characteristics of the vibrating system. Unlike amplitude-frequency curves, amplitude-phase curves of single-degree of freedom systems are single-valued and gently sloping near the resonance for many cases of practical importance regardless of Q-factor and nonlinearity of the vibrating system. The implementation of autoresonant control for the new nonlinear vibratory electro-mechanical systems is described.
