Servo Electric Servo Loading System Design And Research

This paper significantly studies the basic theory of electric loading system, according to guide line of the missile's rudder, designed a electric loading simulation system based on DTC(Direct Torque Control) servo driver. Using the driver of ACS800 to drive asynchronous electromotor, focusing on the controller of TMS320 2812 DSP(Digital Signal Processor), realized the designing of this system. In laboratory the system can simulate accurately the moment which missile's rudder received, it also offers stimulant moment for the designing of missile's rudder, at the same time that can be used to verify it's capability.This paper studies the reason of the plus torque and the method of elimination of the plus torque in detail. In hardware design, this paper introduces the hardware circuits based on DSP TMS320F2812 in detail. And the reliability and antijamming measures of the hardware is explained too. In software design, first the paper discusses the integrated software development environment for Texa Instrument's TMS320C2xx DSP. Then, connected with this system, it introduces each modules of the software, and prognosticate algorithm, table searching algorithm, and other core algorithms of the software. And the bidirectional communications between the computer and load controller is also included.At last, completed some experiments, and analyzed the data, and also gave the simulation of system.At present, the moment to load missile's wings and rudders is relied on fluid driver framework, the paper solves two main problems in electric loading system: the realization of speediness and the elimination of the plus torque. It can provide some new information in load system's further investigation.
