Abstract EN
This paper presents performance characteristics of a new type of direct drive valve (DDV) system driven by a piezostack actuator.
The flexible beam mechanism is employed to amplify the output displacement from the piezostack actuator.
After describing the operational principle of the proposed piezo DDV system, the governing equation of the whole piezo DDV system is then obtained by integrating the equations of the valve components.
Based on the proposed model, significant structural components of the piezo DDV system are designed in order to achieve operational requirements (operating frequency: over 100 Hz; flow rate: 20 liter/Min.).
An optimal design method is proposed for obtaining the geometry of the flexible beam mechanism by considering spool displacement, required operating frequency, and available space of the valve.
After deciding the specific geometric dimensions of the piezo DDV system, a PID control algorithm is designed to enforce the spool position to the desired position trajectories by activating the piezostack actuator.
Characteristics and control performances of the proposed piezo DDV system are evaluated using the MATLAB Simulink.
