Find one (1) type and design of a general close loop control system (e.g. process control, electronic amplifier, mechatronic system, etc.). 3. Model the system using Simulink. 4. Obtain the necessary and suitable output from your model. 5. Design PID controller for the simulated close loop system. Task 2 1. Prepare a block or circuit design, b. Simulink model, c. Simulink results, and d. Possible improvement and applications. 2. Compile the presentation ireport format. Below the is our design

set point:pH7

Input :pH Sensor

controller output :dosing pump

the function:-to regulate water from acid, alkaline dose will up the pH water. The PID will tune dosing pump by frequancy or pulse/stroke

PID constants:- Kp=0.5,Ki=0.2,Kd=0.1
