Patent number: 7535153Abstract: The piezoelectric actuator drive control device has a controller, and executes an initialization process including an optimum phase difference acquisition process P1 and a phase difference inversion detection process P4 at a predetermined frequency. As a result, the optimum phase difference is updated each time the optimum phase difference acquisition process P1 runs to account for wear or temperature change from continuous operation. Furthermore, even if the phase difference between the drive signal and detection signal inverts during a drive frequency sweep due to variation in the vibration characteristic of the piezoelectric actuator, the phase difference inversion frequency and clamping frequency are reset each time the phase difference inversion detection process P4 is executed, thus preventing phase difference feedback control errors.Type: GrantFiled: August 22, 2006Date of Patent: May 19, 2009Assignee: Seiko Epson CorporationInventor: Osamu Urano

Publication number: 20070159507Abstract: A piezoelectric actuator drive control method, piezoelectric actuator drive control device, and electronic device greatly reduce power consumption. The piezoelectric actuator drive control device stores as a speed setting the minimum speed at which a rotor (driven body) turns when driven by the minimum torque required to turn the rotor (S10), and to achieve this speed setting limits the pulse width of the drive signal relative to the reference pulse width of a reference signal (S20). By limiting pulse width to the minimum pulse width required to drive the rotor, the pulse duty of the drive signal in a rectangular wave drive pulse train can be reduced and power consumption can be reduced greatly compared with a drive signal having a 100% pulse duty when the pulse width is not limited. Battery life can therefore be increased.Type: ApplicationFiled: January 3, 2007Publication date: July 12, 2007Applicant: Seiko Epson CorporationInventor: Osamu Urano

Publication number: 20070040871Abstract: A piezoelectric actuator drive control device, electronic device, and piezoelectric actuator drive control method simplify the arrangement of the control circuitry, and enable easily controlling driving a driven body and piezoelectric actuator current. A PWM signal source outputs a variable pulse width control pulse signal B to change the ratio between the periods t-n and t-w when pulse width Nr and pulse width Wd are selected as the pulse width of the drive pulse signal I. This enables the drive control device to freely control the rotor speed and to freely control current flow to the piezoelectric actuator. This arrangement simplifies drive control and eliminates the difficulty of limiting the pulse width and frequency that occurs when directly controlling the drive signal pulse width and frequency.Type: ApplicationFiled: August 21, 2006Publication date: February 22, 2007Applicant: Seiko Epson CorporationInventor: Osamu Urano
