针对陀螺平台视轴稳定系统快速隔离扰动、稳定视轴的要求,设计了以挠性速率陀螺为核心的两轴陀螺稳定平台。结合某光电侦查导引系统设计过程,在多环路从属控制结构中引入内模控制,使位置环、速度环、电流环顺序依次投入运行,以快速的内环路有效抑制干扰,而主环路仍以窄带宽保证跟踪精度,达到了良好的控制效果,满足了高精度光电侦查导引系统对陀螺稳定平台快速性和稳定性的要求。
Aiming at the requirements of fast isolation and stabilization of the optic axis stability system of the gyro platform and the stability of the optic axis, a two-axis gyro stabilization platform with a flexible rate gyro as its core is designed. Combined with the design process of a photoelectric detection and guidance system, the internal model control is introduced into the multi-loop slave control structure so that the position loop, velocity loop and current loop are put into operation in sequence, and the fast inner loop effectively restrain the interference. The main loop The road is still narrow bandwidth to ensure tracking accuracy, to achieve a good control effect to meet the high-precision photoelectric detection and guidance system for the gyro stabilized platform rapidity and stability requirements.
