Assignment Brief and GuidanceHNC/HND Engineering 3Scenario:As an electrical and electronic engineer you always encounter equations, problems and data thatneed to be controlled and analysed in order to understand the results in a practical way. You areworking as an engineer in industry and you have to complete many tasks that you were asked tocarry out. A report must be prepared in order to analyse the results that you have obtained in yourexperiments. From your practical experiences, you must analyse the results carefully usingmethodologies that you have learnt in Industrial systems. This is enhanced by the fact that youhave studied this both theoretically and practically during your studies. Your report must be clearand presented in a professional way as this will have a major impact on how the results areaccepted from practical experiences in the job that you are doing. All the tasks must be finalisedon time and the analysis must be thorough and convincing.LO1: Describe the main elements of an electronically controlled industrial systemTask 1HNC/HND Engineering 4a. Describe the main elements of electronically controlled industrial systems for AC motorsusing both open loop and closed loop control. You must include diagrams and mainconfigurations of these types of industrial control.b. Review the main concepts of electronically controlled industrial systems including types ofmotors and discrete controls system as well as input and output devices used in industrialsystems. Your answer must show the diagrams that fully explain your reviews.c. Analyse the characteristics and the main methods of controlling DC motors in industrialsectors and the practical advantages and limitations of these methods. You must include inyour answers diagrams that explain the methodology used and the main approaches toimprove the performance of these motors in the industrial control.d. Critically examine the controlling methodologies used both in practises and simulations andsuggest further improvements of the main currently used methods. From both practical andsimulation results encountered in your studies what are the advantages and limitations ofusing these approaches over each other in industrial control.HNC/HND Engineering 5LO2: Identify and specify the interface requirements between electronic, electrical andmechanical transducers and controllersTask2a. Identify the requirement of interfacing for discrete automation using relays and solenoid.You answer must show the interfacing between electronic, electrical and mechanical sidesand how the controlling process is implemented.b. Give justifications for the choice of transducers and controllers in a robotic linear motion.Your answer must show the control method used and also the types of transducers used inthis linear motion and the reasons behind this choice.c. Predict the behavior of a pneumatic, hydraulic and electrical actuators by applying differentcontrolling methods. You must give your reasons for choosing any controlling method for aparticular application and ways to improve performance of these methods.d. Critically investigate the behavior of different control system for passive and activeactuators and transducers as well as sensors for temperature and pressure control andgive a full comparison between the different methods including the limitations of theseapproaches.LO3: Apply practical and computer-based methods to design and test a measurementsystemTask 3a. Use a computer software of your choice encountered in your studies to determine theHNC/HND Engineering 6behavior and constancy of the control process of industrial small stepper motors. Include inyour answer accuracy, resolution, tolerances and stability in these systems and how canthese be improved in such systems.b. Explain the use of computer software in practical and analytical methods in order to createand test a measurement and control systems. Your answer must include how uncertaintiesand errors are dealt with in your chosen system.c. Interpret the features and behavior of a chosen electronic measurement systems whichyou encountered in your practical or simulation experiments. Use in your answer differentmethods to find a solution to the accuracy and errors of these devices.d. Using simulation, critically evaluate the performance of a measurement system which youhave used in the experiment that you have carried out during your studies and compareboth the ideal and real circuit. Include in your answer explanations of the errors andaccuracy of this system.LO4: Apply appropriate analytical techniques to predict the performance of agiven system.a. Use a computer software of your choice including Matlab, Simulink, PSPICE and others toanalyse the analytical techniques used in the chosen software in controlling, motors,transducers and actuators. Your answers should explain the performance of these systemsand how these techniques compared to practical measurements.b. Evaluate the features and characteristics of industrial control of induction motors. Yourevaluation should include analytical techniques used for controlling induction motor and thelimitations and advantages of these techniques.c. Analyse the control of large stepper motors in industrial systems. Your answer shouldinclude the appropriate analytical techniques used in this system giving justification andrecommendations in order to improve the performance of such systems.HNC/HND Engineering 7Guidelines for assignment submissiona.
