Abstract
An original control approach for robust vibration isolation is introduced in this paper. Twofeedback signals, the relative displacement and the transmitted force between the sensitiveelement and its disturbing support, are employed in a so-called mixed control design. Thisstrategy is used to perform control in the case of protection of electronic components, suchas frequency generators, vibrating gyroscopes and certain accelerometers, essential tothe operation of electronic cards. The simplicity of the control law allows us totune the parameters of the controller with a very simple optimization process.The proposed isolation control is implemented and optimized for a micromechanicalpiezocomposite structure and the performance and the energy cost are compared withthose of integral sliding control and LMI-optimized control.
