The current loop technique improves the stabilization bed ability to reduce base disturbance direct drive constraint couple and enhances the torque sturdiness . the stabilization error is reduced with current loop technique under same base angular disturbance 在转台稳定系统中使用电流环技术,提高了转台对直接带动约束耦合的抑制能力,提高了系统的力矩刚度,在同等的扰动条件下,降低了稳定误差。
