$($a$)$ Apart from examples provided in lecture notes, explain other $5$ examples of control systems by giving the flow diagrams of systems

$($b$)$ As a graduate of Mechanical engineering with knowledge of control of open loop and closed control systems. Describe atleast $3$ cases that you would prefer to develop control system in each of the following places$/$areas$,$ state why control in needed

$($i$)$ COET UDSM or UDSM

$($ii$)$ Transport System $($Case Dar es salaam$)$

$($iii$)$ Agricultural system $($Case Tanzania$)$

$($iv$)$ Industries where you attended PT training

$($c$)$ From cases above, give advantage of developing the control system and state the type of control you would develop

$($d$)$ Using blocks develop the flow diagram for system functions and the control system diagrams
