Abstract

In this paper, we consider a compensation-type quartz pendulum accelerometer, a feature of which is the use of a digital feedback amplifier in the control loop (for the implementation of a discrete controller and algorithmic compensation for errors from the pendulum unbalance and temperature dependences of the zero offset and scale factor). The problem is related to the construction of a digital control system for the considered accelerometer, which provides a high-precision measurement of the projection onto the sensitivity axis of the actual apparent acceleration of the object on which the accelerometer is installed. A solution to this problem, which allows finding digital control algorithms using various methods of synthesis of discrete controllers of the control loop, is provided. The obtained solutions in the time and frequency domains are analyzed, confirming the high quality of regulation. The results of experimental studies are presented.
