Anti-interference method of shared test equipment for AC servo control system

Abstract

The invention relates to the electromechanical integration electromagnetic compatibility technology in the field of testing, and aims to solve the problem that the weak current part in the electromechanical integration testing equipment is subjected to electromagnetic interference by the strong current part. The invention provides an anti-jamming method for an AC servo control system of a shared testing device. The method includes the following steps: active anti-jamming, passive anti-jamming, and reasonable grounding. Specifically, it is realized through the design of the power supply system of the servo driver, the interface design between the servo driver and the AC servo motor, and the anti-electromagnetic interference design of the interface between the servo driver and the test equipment. Compared with the prior art, the beneficial effect is that the electromagnetic interference problem can be well improved, the interference signal can be controlled within 50mv peak-to-peak value, and basically has no influence on the signal of the product under test and the signal of the test equipment itself.

Description

Anti-interference method for AC servo control system of shared test equipment Technical field The present invention relates to the electromechanical integration electromagnetic compatibility technology of test field, especially a kind of electromechanical integration test equipment Prepare the method for anti-electromagnetic interference design of AC servo control system. Background technique Along with the continuous development of modern weapons and equipment performance and high-end, refinement, before the measurement of unilateral passive type The test equipment can no longer meet the ground test requirements of modern weapon systems in terms of simulation and comprehensive performance analysis. for To improve the automation level of test equipment and improve the authenticity of geodetic data, our test equipment is also constantly improving The degree of simulation and the simulation of the real environment are developed for the purpose. In this way, we will ine...

Yet these methods all are the remedial measures that electromagnetic compatibility is done after equipment development is finished, a bit dead sheep

The nature of mending, although there are some practical effects, but it does not solve the problem fundamentally
