The servo HPVS (hydraulic pressure vibration system) is an important part in control region. The hydraulic pressure vibration platform is considered the controlled object. The design of appropriate platform of controller and implement are the main work. The controlled object HYVP (hydraulic pressure vibration platform) has the property of big loading pressure and rating power, so it need considerable transmitted and control power, it also has the property of high-level math model, and narrow frequency width in closed-loop, and bad stability.This thesis is based on the HPVS in the"Tiema project". It begins with the math model's building, simulation research in theory and half- practicality, then design the appropriate platform of controller, at last it must be verified in the industry local. First calculate the math model of each department of the HPVS, and analyze it's character of the scope with frequency in theory, and base on this some different control methods are designed to resolve the system's stability and expand it's frequency band. The method of adding line trap and acceleration feedback which based on the character of frequency, the method for the problem of designing tracking regulator is transformed to the designing of state adjustor which based on the line system theory, we can get the good control result with these methods. In industry we adopt the method of double close-loop controller because we must consider the technique target and economy target together.It's the core of this thesis that the controller's design with the technology of Digital Signal Processor (DSP). It can not only control the HPVS, but also it can realize the real-time supervise and control on PC. It's one of important features of that the CompactPCI technology which accords with the industry standard. The software of the controller contains the module of communication with PC and the module of servo control.There is an important step which between the simulation in theory and the debugging in industry locale must to be done, the step is electric simulation (it's also mean half-real simulation). Design and produce the HPVS's electric simulate model, combine with the double close-loop controller, Simulate the system's self-excited phenomenon and the badly signal's character, and to find the root reason and the solution method.At last all the results of simulator in theory and electric simulation have been...
