| The performance of linear motor driver directly affects the precision of piston machining, And how to develop the high frequency response and high precision is a direction of the piston machining technology. In this paper, a new type driver of linear motor using a high current power operational amplifier is designed for the purpose of the practical need of the piston machining, therefore the project has realistic significance, and it includes such contents as follows:1. Gives a brief depict about the aim and background of the project. Introducesthe necessary performance of linear motor driver, the domestic and overseas trends of the application on machine of the linear motor driver and the technical aspect related control theory.2. Introduces the design of the new linear motor driver, and analyzes the rationality and feasibility of the design.3. Aims at the necessary performance of the new linear motor driver of the research, some experimentations had been done, include the experimentation of frequency response, the experimentation of linearity degree, the experimentation of square wave inputting, ect. The result of experiments proves that the target of the research has been arrived.4. The feasibility of the new linear motor driver is described by the longitudinal contrasting. The prospect of the research is depicted in the paper also. |
