disturbance control system meaning in Chinese

扰动控制系统

But when come to track space object trajectory , this method is hard to realize good trajectory tracking performance , especially in great variety space object trajectory and severe outside disturbance control system , it is more difficult to improve the capability of trajectory tracking
但是，对于系统的空间目标轨迹，用这种平面轨迹跟踪的方法很难实现其良好的轨迹跟踪运动性能，特别是对于空间目标轨迹变化大、外界干扰严重的控制系统更是难以进一步提高其跟踪性能。
