摘要
为了减小载体扰动对机载光电设备的影响,需要设计保证惯性稳定平台稳定的控制算法。以某型号惯性稳定平台为研究对象,通过建立其机电系统的动态模型,分析了影响平台稳像精度的扰动因素,在此基础上设计了扰动观测器。此外,为有效抑制载体的周期性扰动作用,针对性地设计了重复控制算法。仿真结果表明,所提出的扰动观测器与重复控制相结合的复合控制算法能够有效地抑制载体扰动,提高系统稳像精度。
In order to reduce the influence of carrier disturbances on airborne optoelectronic de-vices,a control algorithm is needed to guarantee the stability of the inertially stabilized platform （ISP）.A type of ISP is taken as the research ob-j ect.Through modeling of its electromechanical system,disturbance factors that affect the image stabilizing precision are analyzed,and a disturbance observer is designed based on this.In addition,a repetitive control algorithm is designed to suppress the periodic disturbance of the carrier.Simulation results suggest that the proposed control algorithm which combines a disturbance observer with the re-petitive control can suppress carrier disturbances effectively and improve the image stabilizing preci-sion.
