Project AIM: To dvelope a simulink model of a DC motor and to design PID control to obtained desired speed of DC motor   Theory and Procedure: Mathematical modelling of a DC motor as per schematic:   From the above schematic diagram we can see that, Vs = Ra*ia + La*d(ia)/dt+vb where, vb=Km*d(theta)/dt and Tou(t)=…

Question 1:   For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations. Solution:   From the screen we can see that EV_default file is loaded abd cargo weight is changed to 500 KG FTP Drive cycle…

Question 1:What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Solution:  Powertrain Blockset provides two types of engine models. Mapped and Dynamic.    Mapped Model: In the mapped models the data is taken from a lookup table characterises…

Question 1:  Which types of power converter circuits are employed in electric and hybrid electric vehicle?    Solution:  Power converters are used in electric/hybrid vehicles to change the form and magnitude of voltage and current fed from and to the vehicle. DC/DC converter - This converts one value of DC voltage into…

Tag the requirements to the simulink model; tagging requirement 1 & requirement 2 to their corresponding subsystems is fine. MBD compliant changes,…

AIM : To create the model and logic of Adaptive Cruise Control (ACC) according to the given requirement data. Objectives:  Developing Adaptive Cruise Control feature as per the Requirement Document using MATLAB Simulink. Follow all the MBD-related processes: Requirement Tagging & Traceability, SLDD creation,…

Question 1: For a defined driving cycle, calculate the energy required for braking. Solution:Calculating the energy required for braking of UDDS Drive Cycle- Braking: Braking is a condition to slow down or stops a moving vehicle as required. There are several techniques to apply brakes, which can be mechanical or…

Project-1: Powertrain for aircraft in runways Objectives: To search and list out the total weight of various types of aircrafts.  To brief differences between ground speed and air speed. Why is it not recommended to use aircraft engine power to move it on the ground at Airport? How an aircraft is pushed to runway…

Question: Explain the various applications of Power converters in an Electric vehicle. For Example what type of converter will you use for Horn which requires DC and less than 10V. Likewise come up with different applications Solutions: There are various types of converters can be used in EV like, DC-DC Converter…
