Design of a liquid level control system to control the water level of a tank
The following information was known about the plant:
Based on the superposition that there is No 'controller' in the system. The reduced diagram would be the multiplication of the plant tranfer functions:
A controller was to be designed to satisfy the following conditions:
- The steady state error of the liquid level in the tank < ±0.5%.
- Settling time < 1.5s
- %OS < 5%.
