A control method and system for improving system response speed

Abstract

The invention provides a control system for improving a system response speed. The system mainly comprises a multichannel servo controller, a multichannel servo signal amplifier, a multichannel servo energy converter, a multichannel integrated device, an execution element, a signal gatherer and a signal demodulator. Any waveform object spectral lines after multiple frequencies are superposed are decomposed into multiple single-frequency driving signals through the servo controller, after the energy converter converts each single-frequency driving signal, the signals are sent to the same execution element for execution through the multichannel integrated device, these driving signals are superposed in the process of being executed, and the purpose of enabling motion output waveforms of the execution element to reach an original object spectral line is realized. The control method and system for improving the system response speed are high in versatility, high in operability, good in controllability, good in reliability and convenient to maintain, can be configured on multiple devices, and can satisfy multiple engineering demands.

Description

technical field [0001] The invention relates to a control method for arbitrary waveform test equipment used in mechanical environment tests, in particular to a control method for improving the response speed of the servo hydraulic part in the arbitrary waveform test equipment and a control system for realizing the method. Background technique [0002] The mechanical environment exists in every aspect of our life, such as the gravity of the earth, the bump of the car, the undulation of the wave, the explosion of the bomb and so on. Arbitrary waveform test system, as a mechanical environment test equipment, is mainly used to reproduce the mechanical environment of objects or products in the service process in the laboratory, to assess the performance of objects or products in this environment, and to improve countermeasures. Arbitrary waveform test system can complete within 200ms (milliseconds), 900m / s 2 The following arbitrary waveform tests are mainly used in reliability t...

Problems solved by technology

At present, the existing relevant equipment on the market are all imported from abroad. The current technology can basically achieve a reversing frequency of 222Hz at a propulsion force of 2150kN or a speed of 90km / h, and this high-response hydraulic servo valve is embargoed in my country. Yes, as far as my country's current hydraulic servo valve technology is concerned, the reversing frequency under the above working conditions can only be 76Hz (not conservative data); if imported ordinary hydraulic servo valves are used, the reversing frequency under the above working conditions can reach 88Hz , there is a huge gap with foreign technology, and this gap has greatly restricted my country's test equipment and technology
