摘要
使用TMS320F2812作为伺服控制器,设计了一个小型而又简单的伺服系统。通过频域法得到控制对象的数学模型,使用精密电位计作为位置传感器,形成位置闭环。进行超前-滞后的校正补偿,实现对系统的任意角度的控制。在0.1°的阶跃信号输入下,得到调节时间ts为0.44 s,位置误差Ess为0.058 8°的控制特性,其特性参数满足指标要求。实践表明该位置环设计是有效的。
A simple servo system was designed, and TMS320F2812 was treated as the servo controller. The math model was obtained by the method of frequency-domain, a fine potentiometer was used as a position sensor to form the position closed loop. The angle is under the control by the compensation of lead-lag correction. With the input step signal of 0. 1°, the adjustable time is 0. 44s, position error is 0. 058 8°, which meets the need of system. It proves that the design of position closed loop is effective.
