The system in the figure is controlled by the PID controller. Find the PID control parameters with the Ziegler-Nichols method for the most appropriate control of the system

Explain the fundamental differences between open-loop and closed-loop control systems. Provide examples of each and discuss the advantages and limitations of both approaches.

In swimming pools and water tanks, the water level needs to be controlled. To manage the water level, a water level controller device is used. The aim of water level controller is to adjust water flow and improve the functioning. For the water level closed loop system shown in figure Q4, analyze the following basic components of the system: (1) Controlled variable (ii) Reference variable (ii) Comparison element (iv) Error signal (v) Control unit Hollow ball Lever Water input Pivot
