For two kinds of servo systems that the output can be directly measured or not directly measured, the direct compensation method and the BP neural network compensation method for backlash nonlinearity were presented. Simulation results for a tank barbette tracking system show that these two kinds of compensation methods can successfully eliminate the influences produced by backlash nonlinearity, and improve the system accuracy.

Toady's DVD-ROM manufactures still use the bilinear transformation to design servo controller in w-plane. In the special purpose servo chip for the DVD-ROM, because of the effect of the structure of the controller and the limits of the chip, the result of the controllers may not be implemented in the chip after designing, and redesigning is regained again and again.

目前产业界设计DVD-ROM伺服控制器仍采用双线性转换，经转换后在w平面上设计控制器，但由於受到专用控制晶片的控制器结构与限制的影响，在设计后可能无法直接套用至晶片上使用，而需反覆设计。
