摘　　要：针对仿真转台计算机控制系统的要求,采用集散控制系统(DCS)机制设计计算机控制系统。提出了一种采用复合PID算法的变结构控制、速度内环与位置外环的双闭环控制结构相结合的方法,并引入PI-P调节器显著提高系统精度。采用顺馈技术提高系统的阻尼比来改善系统带宽,增大比例增益和提高积分作用来提高系统低速随动性能。检测结果表明:转台频带测试相位误差为2.4%,幅度误差为7.4%,并能以0.048°/s的低速平稳运行。The computer control system is designed by distributing control system （DCS） structure in the view of the requirements. A method by combination of compound configurable PID control, twin-closed-loop of speed inner-loop and position outer-loop control structure is proposed. Through introducing PI-P regulator to improve the system precision. The damp ratio is promoted by feed-in technique to improve the system bandwidth. By increasing the proportion gain and integral function the low-speed follow-up performance is improved. The results of test show that the phasic error of bandwidth is 2.4 %and the magnitude error is 7.4%. The turntable is able to work steadily at the low rate of 0.048°/s.
