Embodiment

[0198] Example: The DTS200 three-capacity water tank system produced by Amira Automation in Germany is a multi-input and multi-output non-linear experimental system. figure 2 Shown. The experimental platform consists of three cylindrical glass water tanks, from right to left, there are water tanks 2, 3, 1 in order. Any two water tanks are connected by a connecting pipe equipped with a ball valve, and water tank 2 is connected to the bottom reservoir. The water in the reservoir can flow directly to the reservoir through the connecting pipe, and the water in the reservoir can directly use pump 1 and pump 2 to enter the water tank 1 and water tank 2. The differential pressure transmitter is used to measure the liquid level of each water tank, pump 1, 2 can be used to control the liquid level of water tanks 1 and 2, but the liquid level of water tank 3 is not controlled. It is possible to manually control the opening and closing of valves, adjust the gain knob of the water tank co...

Abstract

The invention discloses a fault detection method for solving a system with a self-triggering transmission mechanism based on a convex polytope theory. The fault detection method comprises the following steps: S1, establishing a continuous system model containing interference input and faults and discretizing the continuous system model; S2, designing a fault detection filter, and deriving a stateestimation error system; S3, processing the error system by using a convex polytope theory, and defining random stability and H_/H infinity performance constraints; S4, solving a linear matrix inequality to obtain the parameters of the fault detection filter; S5, designing a self-triggering transmission mechanism; and S6, substituting the parameters obtained in the above step into the fault detection filter to carry out fault detection.

Description

Technical field [0001] The invention relates to the fault diagnosis field of known system mathematical models, such as three-capacity water tank systems, power systems, and the like. Specifically, it relates to a fault detection method for solving systems with self-triggered transmission mechanisms based on convex polytope theory. Background technique [0002] With the continuous development of modern technology, modern industrial systems are becoming more and more complex and costly. Once the system fails, it will not only cause huge economic losses, but even endanger the lives of workers. This requires the system to have higher security, stability and reliability. Fault diagnosis technology is playing an increasingly important role in industrial production, and many research and production practices show that fault diagnosis technology has very important practical significance. [0003] In a networked control system, due to bandwidth limitations, data transmission will be subjec...
