Embodiment

[0032] figure 1 It is a structural diagram of the position loop performance index test system of the position servo system, in which the test signal output module, the response signal acquisition module and the communication transmission module are formed based on FPGA (programmable gate array). In this example, the FPGA selects the CYCLONE II series chip EP2C5Q208C8 of altera company. The test signal output module is connected with the data processing module, and generates test signals according to the test parameters input by the man-machine interface module. The response signal acquisition module is connected with the data processing module, and is used for digital sampling of the collected response signal. The communication transmission module is used to transmit test signals and response signals, and complete the interface with the servo system and the conversion of data formats. The communication transmission module mainly has the following two functions: one is to rece...

Abstract

The invention relates to the positional servo technology, especially to a position loop performance test method of a positional servo system and a test system thereof. The invention discloses a test method for a position loop performance index of a positional servo system and a test system thereof, so that a position loop performance index of a positional servo system can be effectively and rapidly tested; therefore, the test method and the test system are suitable for testing in positional servo system research and development of aviation, aerospace, and a high precision machine tool and the like and on-site testing. According to the position loop performance test method provided by the invention, a time domain test signal or a frequency domain test signal is input in a positional servo system; a response signal that is output by a position loop of positional servo system is collected; and the response signal is analyzed and calculated, so that a time domain performance index and a frequency domain performance index are obtained, wherein the time domain performance index and the frequency domain performance index can reflect performances of the position loop as well as can be concrete parameter indexes and/or wave curves.

Description

technical field [0001] The invention relates to position servo technology, in particular to a position loop performance test method and test system in a position servo system. Background technique [0002] The position servo system with the goal of fast and precise is playing an increasingly important role in the fields of aviation, aerospace, and high-precision machine tools. The position loop is the outermost loop of the position servo system, and it is also the final application end of the position servo, which is closely connected with the load. The performance of the position loop is directly related to the external application characteristics of the position servo system. Therefore, it is of great significance to test the performance index of the position loop of the position servo system. [0003] The position loop performance index test system of the position servo system can test and evaluate the position loop of the position servo system. Performance indicators ...
