# Liqiud Level Control System

Design of a liquid level control system to control the water level of a tank

![Block diagram](https://github.com/aniekanBane/Liqiud-level-control-system/blob/main/images/Block%20diag.png)

The following information was known about the plant:

## Block reduction

Based on the superposition that there is No 'controller' in the system. The reduced diagram would be the multiplication of the plant tranfer functions:

## Controller

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%.

## Stability
