Looking for an example of three impulse control. Thank you
Three-element control for the liquid level regulation of the high-pressure drum, which consists of the drum pressure, liquid level, and boiler feedwater flow rate.
The water level in the boiler drum is controlled by three-element regulation.
The “Petroleum and Chemical Industry Automatic Control Design Manual” (3rd edition) provides detailed information on this topic
Air vessel level, steam flow rate, and make-up water flow rate. Sometimes, there is also a compensating fluid level based on the pressure in the air pocket. Check the requirements of the patent holder!
