Abstract: Automatic lowering system is usually a significant process in the course of complete automation of gyroscope. In view of the current gyroscopes, an automatic lowering project is proposed based on camshaft under the control of rotary stepped motor, and the fixing structure is designed as well as the whole control system. By analyzing influence factors during the course of lowering, the relationship between initial condition of gyroscope and half-away position while lowering is obtained through a lot of experiments when the swing is within the ideal range. Based on this, the adaptive intelligent motion control system is proposed, i.e. a lowering speed scheme database is built on the basis of the relationship between the initial condition and half-away position. For different initial conditions, corresponding half-way positions are automatically inquired, then the motor speed is set, thereby realizing intelligent control. Through tests of stability, swing range and repeatability of the automatic lowering system, it is shown that the gyroscope is always in normal working range with different conditions and its running is stable, which proves that the control system is effective and reliable. By the project, the bottleneck of swing control in automatic lowering is solved effectively, the automation level and the measurement accuracy are improved significantly.
