Control system stability analysis method and device and computer-readable storage medium

The invention discloses a control system stability analysis method, a control system stability analysis device and a computer-readable storage medium, and the core idea is as follows: by constructinga Kronercker-Lyapunov matrix, the boundary values of uncertainty parameters when a control matrix is located at stable and unstable critical positions are calculated by using the Kronercker-Lyapunov matrix, and finally the stability interval of a control system is calculated through the boundary values. According to the method, an automatic system with a feedback function is effectively controlled, and the key point is that the control system is ensured to operate in a stable interval, so that the control system can be effectively controlled all the time when the stable interval is obtained, high-quality production is realized, and the production efficiency is improved. The calculation method is simple and clear, is low in calculation complexity, and has a good help effect on the judgmentwork of the stability inte
