From the experiment and analysis, it can be seen that friction limits realization of high accuracy electro-hydraulic position servo system, movement of any gimbal brings disturbance moment to servo system of other gimbals and the disturbance moment causes error, and, resolution ratio error and setting error of feedback measurement element are directly added to servo system output.

通过实验和仿真可以看出，摩擦阻碍了转台电液位置伺服系统商精度控制的实现，任何一个框架的运动都会对其余框架的伺服驱动系统产生干扰力矩并引起伺服系统误差，反馈测量元件的分辨率误差和安装误差直接反映在伺服系统输出上，对伺服系统的精度有直接影响。

By comparison with conventional hydrostatic transmission, its power matches load well because it is adjusted by servo system. By comparison with secondary adjusting system being applied in industry newly, HESTS not only adjusts operation mechanism to match the system output and load well, but also adjusts engine or hydraulic pump, and manipulates the direction of power flow inputing or outputing the Energy Storage Unit actively. Therefore, HESTS can get energy of whole system matched well, increase the efficiency of system and performance of main machine. First, a HESTS applied in vehicle was designed.

由于对执行机构采用自动调节，系统的功率匹配合理，效率有较大提高；同新近发展起来并已被应用的二次调节系统相比，静压储能传动不仅通过调节执行机构来达到系统输出与负载的良好匹配，而且还调节原动机或液压泵，以及主动控制系统中储能元件的能量流动，因此能达到整个系统的能量合理分配，从而提高了系统的效率和整机的性能。

However, the poly-Si TFTs suffered poor uniformity with large variations on the device characteristics due to the narrow laser process window for producing large-grained poly-Si TFTs.
