摘要:
低频采样和延迟对光电成像跟踪系统会带来严重的相位滞后,极大地限制了系统闭环带宽和跟踪精度的提高.零极点对消法虽可以抑制对象谐振而扩大系统带宽,但必须依赖精确的数学模型和较高的采样频率.分析了复数零点PID控制器在低频采样的FSM控制系统中的应用,可以获得较好的闭环性能而且可以避免零极点对消法无法单独应用于低频采样的跟踪系统的问题.采用200 Hz帧频的CCD对此方法进行了实验验证,实验结果证明满足设计要求.
Abstract:
Low sampling frequency and delay may introduce severe phase lag in photoelectric imaging tracking control system, which restrains the closedloop bandwidth and tracking precision of the tracking control system. Zerospoles cancellation applied in this system can cure for resonance to widen the bandwidth of the system, but this method must rely on the precise mathematical model and relatively higher sampling frequency. A PID controller with complex zeros is analyzed for the appliance in fast steering mirror(FSM) system based on the CCD with low frame frequency; furthermore, good closedloop performance is achieved by means of this controller. However, zerospoles cancellation cannot be applied in the tracking system with low sampling frequency without other assistant method. The 200 Hz CCD was used in FSM tracking experiment to verify the method and the experiment result shows that the performance satisfies the design requirements.
