Embodiment Construction

[0053] A method for judging the non-sensitive area of ​​a steering gear system will be described in further detail below in conjunction with specific embodiments. These embodiments are only for the purpose of comparison and explanation, and the present invention is not limited to these embodiments.

[0054] A method for judging the non-sensitive area of ​​a steering gear system, such as figure 1 As shown, the method includes:

[0055] Step 1. Input the unit angle wave control signal to the steering gear system to obtain the feedback signal of the steering gear system;

[0056] Step 2. Filtering the feedback signal;

[0057] Step 3. Based on the preset insensitive zone threshold range, the filtered feedback signal is judged to obtain all static zones of the steering gear system;

[0058] Step 4. Obtain the maximum non-sensitive area of ​​the steering gear system according to the time corresponding to the largest static area in all static areas;

[0059] Step 5. Perform error c...

Abstract

The invention discloses a method for judging a non-sensitive area of a servo system and belongs to the technical field of servo system control. With the method adopted, the problems of inaccurate judgment and low judgment efficiency of the non-sensitive area of a servo system in the prior art can be solved. The method comprises the following steps that: unit angle wave control signals are inputtedto a servo system, so that the feedback signals of the servo system can be obtained; the feedback signals are filtered; the filtered feedback signals are judged on the basis of a preset non-sensitivearea threshold value range, so that all the static areas of the servo system are obtained; the maximum non-sensitive area of the servo system is obtained according to a time point corresponding to the maximum static area in all the static areas; error correction is performed on the maximum non-sensitive area of the servo system, so that the corrected non-sensitive area of the servo system and thestarting point and duration of the non-sensitive area of the servo system are obtained. The method is suitable for judging the non-sensitive area of the servo system.

Description

technical field [0001] The invention belongs to the technical field of servo system control, in particular to a method for judging an insensitive area of ​​a steering gear system. Background technique [0002] The steering gear system is an important part of the guidance and control system in modern intelligent ammunition such as autonomous attack ammunition, corrected ammunition, ballistic correction fuze, and guided submunition. Electric steering gear has attracted people because of its simple structure, good craftsmanship, high reliability, low cost, single energy source, fast frequency response, strong load capacity, high control precision, convenient use and maintenance, and easy integration with the missile-borne computer. extensive attention and in-depth research. [0003] The steering gear is the executive mechanism of the intelligent ammunition guidance and control system, and its performance will directly affect the dynamic quality of the intelligent ammunition fl...
