Implementation Options of Control Systems for a Cantilever Calibration Device

Abstract

The article describes global approaches to control of the cantilever calibration device. The idea of the device consists in electromagnetic compensation of the influence of cantilever forces. The development of regulators is based on the simulation of mechanical processes when the cantilever is applied to the load cell with the principle of electromagnetic compensation; the identification of the processes is performed. In addition, in the course of the study, a comparison was made of PID controllers implemented on various actuator systems: an analog circuit, a current source, a dSPACE real-time system, a microcontroller. The purpose of developing and comparing regulators was to improve characteristics of the system: regulation time, overshoot, noise amplitude.
