Brief introduction of control mode · Open loop control of controller / host computer User can isolate drive channel and sensor channel through controller or host computer. The drive module is used to control the workbench, and the sensor module is used to measure the control results. In this state, the user can complete the study of the open-loop hysteresis, creep, temperature, and electromechanical characteristics of the piezoelectric ceramic actuator.
· Closed-loop control of controller / host computer The user can use the digital PID algorithm of the controller to input the desired target positioning value using the host computer or controller keyboard to complete the closed-loop control, and output the control results to the controller for display or transmission to the host computer machine.
· Analog open-loop / closed-loop control The user can choose the control method to conduct analog open-loop or closed-loop control experiments through the analog output of the sensor module and the analog input signal of the drive module.
