以单轴稳定平台为对象,研究分析不同类型外界干扰力矩作用下,惯性平台稳定回路控制律形式对平台稳定精度的影响。采用高阶型控制律,更有利于实现对干扰力矩的抑制,尤其是在有较大过载变化的应用环境,或存在较大偏心不易精确平衡的情况下,需要适当提高控制律的阶次来提高平台的稳定精度。仿真结果说明,在与过载有关的干扰力矩作用下,稳定回路控制律的积分校正阶次越高,平台的稳定精度越高。
Taking a uniaxial stable platform as an example, the influence of the steady loop control law of the inertial platform on the stability of the platform under the influence of different types of external disturbance torque is studied. The higher-order control law is more conducive to the suppression of the disturbance torque, especially in the application environment with large overload change or the situation that the larger eccentricity is not easy to be precisely balanced, and the order of the control law needs to be appropriately increased Improve the stability of the platform. The simulation results show that under the disturbance torque related to overload, the integral correction order of the stability loop control law is higher, and the stability of the platform is higher.
