Keywords:Inertial navigation system, Gyroscope, Accelerometer, Gyrostabilized platform, Alignment, Gyrocompassing, PID-control
Background. Alignment of inertial navigation system has vital importance to inertial navigation system, because precision navigation depends on the process time and alignment error.
Objective. The purpose of our paper is to research possibility to use PID-control for initial alignment of inertial navigation system. Two alignment modes – leveling and gyrocompassing of platform are discussed.
Methods. Literature review on alignment and state of problem are considered in the first part – introduction. The second part of the paper presents details of standard gyrostabilized platform leveling by scheme “accelerometer–gyroscope–platform”. In the third part a possibility to use PID-control for coarse leveling by “accelerometer–platform” scheme is discussed. Gyrocompassing mode is the subject of the last fourth part.
Results. Calculation formulas for determining the coefficients of the PID control, dynamic and precision characteristics of gyrocompassing mode for gyroscope proportional control law are obtained. The results of computational modeling of the process of leveling for multiple selection criteria of the coefficients of the PID-control are brought.
Conclusions. It is concluded that using of standard Butterworth forms and integral criterion of minimum weighted error module allows us to bring and provide the necessary precision. Using the PID-control for the coarse leveling mode ensures the necessary control process quality.
