The speed and position double close-loop control is commonly applied in the TV tracking system. The feed forward control can improve the tracking precision but be unrealizable. The speed and accelerated speed delay compensation can do the same just in a limited range. The Dynamic High Type (DHT) control is to add some integral sections in the feed back control system for improving the precision. With the increase of both object speed and automatic tracking ability of the optoelectronic tracking equipment, higher precision is needed for the servo system in the TV tracker. Here, we put forward a ramp accumulated compensation method, which is verified by both the theory and simulation, that it is similar to DHT control. Accordingly, DHT control can be explained in a new point of view, and we offer the theoretical foundation for DHT realization in the engineering to improve the tracking precision of the TV tracker.

电视跟踪系统通常采用速度、位置双闭环控制。前馈控制可以提高跟踪精度但无法实现;速度、加速度滞后补偿,跟踪精度提高有限。动态高型方法是在负反馈控制系统中增加若干积分环节以提高跟踪精度。随着目标速度的提高和光电跟踪设备自动化程度的提高,对电视跟踪器伺服系统的跟踪精度提出了越来越高的要求。本文创新性引出一种斜坡累加补偿方法,通过理论证明和仿真,指出它与动态高型技术高度相似,从而从新的角度解释了动态高型提高跟踪精度的机理,并为动态高型方法在工程上实现电视跟踪伺服系统的跟踪精度的提高提供了坚实的理论依据。
