Abstract Details

2007, Master of Science, University of Akron, Electrical Engineering.
This thesis presents a charge feedback method for linear control of a piezoelectric stack actuator. The charge feedback control system incorporates a high-impedance, high-voltage charge sampling circuit, a window comparator, and a low-resistance, switched-mode (non-PWM) actuator drive circuit. The system design and modeling are discussed in detail. A describing function stability analysis is performed to determine the allowable variations in the comparator dead zone and the actuator drive circuit propagation delay. Experiments were conducted to compare the responses of the stack actuator under voltage and charge control and to determine the frequency and amplitude limits of operation. The experimental data show that the charge control provides nearly linear actuator operation from 0.1 Hz to 10 Hz over 66.7% of the actuator operating range, and from 0.1 Hz to 100 Hz over 56.7% of the operating range. The constrained displacement range is found to be a function of the actuator drive circuit and charge sampling circuit implementations, and therefore not a general limitation of the presented charge control design.
