Abstract
A control scheme is designed for the purpose of suppression of vibratory motion of a dynamical system. The efficacy of robustness of the controller vis a vis unknown but bounded disturbances and state measurement errors is investigated analytically and numerically. As an example of a dynamical system we consider a single degree of freedom mass-spring-damper system which is excited by an unknown force. The control scheme presupposes that the spring and damping coefficients can be varied within prescribed bounds, albeit not independently. The construction of such a semiactive controller can be realized by using the properties of so-called "electrorheological" fluids; see [2] for relevant experimental investigations. The called for changes in spring and damping properties can be effected in microseconds since the control does not involve the separate dynamics (inertia) of usual actuators. The design of the controller is based on Lyapunov stability theory which is also utilized th investigate the stabilizing properties of the controller. To accomodate state measurements errors the proposed control scheme is combined with a "fuzzy control" concept. Simulations are carried out for examples of periodic, continous non-periodic, discontinous perodic and random excitation forces.
