基于C51单片机的精密达位电动转台控制系统设计

his paper presents a design of control system for electro-turntable of precise position based on C51 microcontroller. In the control loop, we accumulate the error information of angular position according to the given value and feedback value, and the controlled variable, which is derived from the PID control algorithm based on humanoid control, is transported into power amplifier to drive the turntable to a precise position. The turntable has a good real-time property, because we absolutely use assembly language programming in control software of this design. It has been successfully applied in a certain electro-turntable control system, and the practice verified that this kind of turntable control system is economical and practical, and it’s applicable to turntable control system which doesn’t demand a high dynamic performance.
