伺服俯仰平台对位置、速度控制的精度、响应时间要求很高,俯仰传动过程复杂,控制系统的传递函数难以建立。本文应用LabWindows/CVI交互式开发平台,搭建硬件控制平台,对俯仰平台的运动控制系统进行数学模型设计,并通过仿真,给出了满足要求的PID控制参数,设计了俯仰平台软硬件控制系统。实践证明:基于labWindows/CVI设计的俯仰控制系统能够满足控制系统精度和响应时间的要求,且具有操作简单、调试方便、控制准确的特点。
Servo-tilt platform position, speed control accuracy, high response time, pitch transmission process is complex, the transfer function of the control system is difficult to establish. In this paper, a LabWindows / CVI interactive development platform is set up, a hardware control platform is set up, and a mathematical model of the pitch platform motion control system is designed. The PID control parameters that meet the requirements are given and the software and hardware control system of the pitch platform is designed. Practice has proved that the pitch control system designed based on labWindows / CVI can meet the requirements of control system accuracy and response time, and has the characteristics of simple operation, convenient debugging and accurate control.
