Abstract
A control system for implementing nonlinear interference compensation for a torsion angle of an astronomical telescope is provided. The system includes a torsion angle detection system and a torsion angle compensation and amendment system. The torsion angle detection system is provided with a measurement mechanism for measuring the position of a driving wheel, and a position signal of the measurement mechanism is fed back to an industrial personal computer in the torsion angle compensation and amendment system in real time. An output signal of the industrial personal computer controls a compensation motor to rotate, and the compensation motor inclines an elastic plate with the driving wheel mounted thereon through a transmission mechanism, to further cause the torsion of the driving wheel by an angle and form compensation to the torsion angle.
