The holistic design of the system and resolved the designs of software and hardware based on VXI bus are put forward according to the demand of test system. The hardware and software is designed, including the formation and design of hardware system, visual instrument software architecture, program design for instrument driver, high speed real-time data collection. In the dynamic test program, the idea of"software is instrument"was applied to meet the diverse test demands. Last, it is proposed that the VXI test system be developed to more totalization and networked. The basic theory of system identification was introduced briefly at first. The principle of spectrum analysis system identification based on Wiener-Hopf equation was expatiated. and the questions in applying Peusdo Random signal as spectrum analysis methods stimulate signal was studied, The generation principle of the peusdo random signal is researched, the characteristic of peusdo random are analyzed from time domain and frequency domain, the inverse repeat peusdo random signal is brought forward to make up the shortage of ordinary peusdo random signal. And a new chaos genetic algorithmis presented to solve the unprecise problem of the traditional method. In the servo valve dynamic characteristic test system, the spectrum analysis methods was applied successfully, the servo valve dynamic characteristic could be acquired rapidly and exactly, the test results were analyzed and the ameliorate methods were brought forward at last.

Hence, a self-balancing controller is implemented by considering the motion as well as configuration variation of the upper body (the 9-DOF mechanism). The control law utilizes the principle of computed torque method with online identification of related parameters using various sensors including an accelerometer. The incline angle is obtained by fusing a gyroscope and a tilt sensor. Under the balancing control, the forward motion of the robot is achieved by giving a desired tilt angle profile.

除此之外，本作品将此机器人装置在一具二轮式自动平衡移动平台之上，它提供了机器人灵活移动和转身的能力，但碍於此一平台本身为不稳定系统，所以必须实现一自动平衡演算法去计算底座以及上半身机器人动作行为的转动力矩，利用计算转矩法以及陀螺仪、倾斜仪和加速规去即时更新系统参数，让整个系统可以即时地保持平衡，并且利用设计角度值的概念让整个系统移动。

For example, as used by Audi, a five-speed Tiptronic will make the upshifts from 1 to 2 automatically when moving off from a stop even when in Tiptronic mode; the transmission then waits for the user's upshift command before proceeding from 2 to 3, 3 to 4 and 4 to 5, although the transmission will still upshift if the redline is approached.

举例来说，Audi使用的一种5速Tiptronic变速器将在起步时自动进行由1挡到2挡的升挡，即便其尚处于Tiptronic换挡模式；变速器在进行2到3、3到4、4到5挡换挡前等待使用者的换挡命令，而在接近转速红线时自动升挡。

A Tiptronic transmission can operate just as the common type of automatic transmission, but it also allows the driver to override the automatic mode by moving the shift lever into a second shift gate equipped with two spring-loaded positions:"upshift" and "downshift".

Tiptronic变速器可以像普通自动变速器一样工作，但其也可以让驾驶者通过移动挡杆移入第二种换挡方式而超越自动模式进行操作，该换挡方式具有"升挡"和"降挡"两个弹簧负载的位置。
