摘要： A drive circuit (18) produces a drive signal having a waveform of a predetermined waveform shape for a device (10) having a piezoelectric actuator (14). The drive circuit (14) includes a memory (140) which stores waveform shape data which is utilized by the drive circuit in producing the drive signal. The drive circuit utilizes the waveform shape data so that, for each of plural points comprising a period of the waveform, the drive signal has an appropriate amplitude for the predetermined waveform shape. The waveform shape data has preferably been prepared to optimize one or more operational parameter(s) of the device. Preferably the waveform shape data has been prepared by solving a waveform equation, the waveform equation having coefficients determined to optimize at least one operational parameter of the device. The number of coefficients determined for the waveform equation depends on the number of harmonics of the waveform that are within a bandwidth of the device. Other aspects concerns devices which utilize the drive circuit, methods for operating devices, the memory (212) which is utilized by the drive circuit (e.g., the drive circuit which produces the drive signal for the device having the piezoelectric actuator) to store the waveform shape data, as well as apparatus and method for generating the optimized waveform shape data.

摘要： Actuator assemblies comprise an actuator element and two piezoelectric assemblies, with the two piezoelectric assemblies being configured and arranged for controlling movement of the actuator element. In some example implementations, the first piezoelectric assembly and the second piezoelectric assembly are constructed and arranged so that a temperature dependency of the first piezoelectric assembly is cancelled by the temperature dependency of the second piezoelectric assembly. In a first example embodiment, a first piezoelectric assembly comprises a first or main piezoelectric diaphragm connected to the actuator element for displacing the actuator element in response to displacement of the first piezoelectric diaphragm. The first piezoelectric diaphragm is mounted to a movable carriage. A second piezoelectric diaphragm, which comprises the second piezoelectric assembly, is connected to the carriage for displacing the carriage in response to displacement of the second piezoelectric diaphragm. A driver applies electrical signals to the first piezoelectric diaphragm and the second piezoelectric diaphragm for causing the first piezoelectric diaphragm and the second piezoelectric diaphragm to displace in the same direction. In a second example embodiment, the actuator element is at least partially situated in a housing wherein the actuator element is capable of reciprocating movement. Within the housing the actuator element at least partially defines a first variable fluidic chamber and a second variable fluidic chamber. The first piezoelectric assembly comprises a first variable reservoir connected to the first variable fluidic chamber; the second piezoelectric assembly comprises a second variable reservoir connected to the second variable fluidic chamber. A first working fluid occupies the first variable reservoir and the first variable fluidic chamber; a second working fluid occupies the second variable reservoir and the second variable fluidic chamber. A driver applies signals to the piezoelectric material comprising the first variable reservoir and the second variable reservoir for causing the first variable reservoir to contract and the second variable reservoir to expand during an extension movement of the actuator element, and for causing the first variable reservoir to expand and the second variable reservoir to contract during a withdrawal movement of the actuator element.
