Description

technical field [0001] The invention belongs to the field of control theory and control engineering, in particular to an event-triggered control method and control system based on switching RLC circuit systems. Background technique [0002] With the rapid development of electronic technology, the functions of electronic equipment are increasingly rich and complex. Many circuits require different working modes, and different working modes correspond to different functions. For such application requirements, various solutions for switching circuitry have arisen. RLC circuits with arbitrary switching characteristics are often used in integrated circuits to perform low-frequency signal processing, therefore, switched RLC circuit systems have become a current hot research direction. However, the RLC circuit system with arbitrary switching characteristics is a nonlinear time-varying system, which cannot be analyzed and controlled by classical control theory. The complexity of its...
