Multivariable Lqg Vibration Control Using Charge-driven Piezoelectric Actuators
Piezoelectric actuators are known to exhibit hysteresis when driven at relatively large voltages. In most situations this phenomenon is detrimental. Electric charge is known to naturally reduce the effects of hysteresis. The interaction of charge driven piezoceramics with flexible structures is analyzed and reveals that the dynamics of the system are different from the voltage driven case. A pr...
متن کاملControl of Piezoelectric Actuators Using Analog Sliding Mode Controller
This work aims the precise control of the piezoelectric actuators that can theoretically provide unlimited motion resolution. For this purpose Sliding Mode Controller (SMC) is used. The proposed algorithm is known to have order of sampling time square and therefore faster application than DSP was required. The application of the algorithm via analog electronics is suggested. Preliminary work, s...
متن کاملShape control of a beam using piezoelectric actuators
This paper presents the analytical and experimental results on optimal placement of piezoceramic actuators for shape control of beam structures. The objective is to determine the optimum piezoceramic actuator locations and voltages to minimize the error between the desired shape and the achieved shape. The analytical model for predicting beam deformation due to a piezoelectric actuator is based...
متن کاملMultiRate Predictive Control of Piezoelectric actuators
Piezoelectric materials show nonlinear hysteresis behaviour when they are under high electrical field and mechanical load. Fundamental study of PEA depicts that the Hysteresis effect deteriorate the tracking performance of The PEA. This paper proposes a nonlinear model which quantifies the Hysteresis nonlinearity generated in Piezoactuators in response to applied driving voltages. A novel perfe...
متن کاملFPGA-Based Control of Piezoelectric Actuators
Abstract: In many industrial applications like semiconductor production and optical inspection systems, the availability of positioning systems capable to follow trajectory paths in the range of several centimetres, featuring at the same time a nanometre-range precision, is demanding. Pure piezoelectric stages and standard positioning systems with motor and spindle are not able to meet such req...
