Abstract

The invention discloses a mixing process control experimental apparatus. The mixing process control experimental apparatus comprises a water storage tank as well as a first water groove and a second water groove which are connected with each other sequentially through a pipeline with electromagnetic valves; the first water groove is provided with a water inlet and a water outlet, wherein the water inlet is connected with a first heating device, the water inlet is connected with the water storage tank through a water pump; a stirrer is installed in the first water groove; a stirrer and a second heating device are installed in the second water groove; and the second water groove is provided with two water inlets and a water outlet, wherein one water inlet is connected with the water outlet of the first water groove, the other water inlet is connected with the water storage tank through a water pump, the water outlet is connected with the water storage tank through an air-water heat exchanger and a water pump sequentially. According to the mixing process control experimental apparatus of the invention, the opening and closing of the electromagnetic valves are adjusted through a control system, so that a mixing procedure control process can be simulated flexibly, and the design and test of control algorithms under different complexities can be realized, and an experimental apparatus emphasizing algorithm test and execution in actual conditions can be provided for researchers of related theories.

Description

technical field [0001] The invention relates to the field of process control, in particular to a hybrid process control experimental device. Background technique [0002] A hybrid system is a dynamic system formed by mixing a discrete event system with a continuous variable system, which is characterized by being both continuously changing over time and driven by discrete emergent events. There are many examples of hybrid systems, such as automobile control systems, aircraft control systems, steam boiler systems, and some chemical production and processing devices with batch and intermittent characteristics. [0003] Research on the process control of hybrid systems is mostly concentrated on the theoretical level, such as modeling of hybrid systems, stability research of hybrid systems, and optimal control of hybrid systems. The process control training system developed by a teaching instrument company simulates the actual industrial production and processing process throug...
