Description

technical field [0001] The invention relates to a chaos stirring control system based on ARM single-chip microcomputer chaos mapping control. Background technique [0002] Mixing equipment has a long history of use and is widely used in chemical, pharmaceutical, food, paint, wastewater treatment and other industries. In these industries, mixing operations of medium and high viscosity materials are often carried out. Since the material is often in a laminar flow state, a large-scale mixing isolation area is formed near the upper and lower sides of the agitator blades during conventional uniform stirring, resulting in uneven mixing in the stirring tank for a long time, high energy consumption, and low mixing efficiency. In order to improve the effect of industrial mixing, researchers have studied the mixing characteristics of non-traditional mixing methods, such as variable speed stirring, eccentric stirring, etc. The study found that these unconventional stirring methods ca...

Problems solved by technology

This patent uses the circuit itself to generate chaotic signals. Although it can control the chaotic speed of the motor, it uses the instability of the circuit itself. The method described in this patent is difficult to implement, requires complex control circuits, and requires high circuit technology for the operator.

After the circuit design is completed, the types of chaotic signals cannot be adjusted manually
