Week 3 - Solving second order ODEs

1.list out the total weight of various types of aircrafts.  The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation.[1][2][3] An aircraft's gross weight will decrease during a flight due to…

For a defined driving cycle, calculate the energy required for braking. The function of the braking system is to retard the speed of the moving vehicle or bring it to rest in the shortest possible distance whenever required. The vehicle can be held on an inclined surface against the pull of gravity by the application of…

3.Explain in a brief about operation of BLDC motor. A brushless DC motor (also known as a BLDC motor or BL motor) is an electronically commuted DC MOTOR which does not have brushes. The controller provides pulses of CURRENT to the motor windings which  control and torque of the synchronous motor: These types of motors…

2.  An Electric Vehicle's powertrain with 72V battery pack in shown in the diagram below. The duty ratio for acceleration operation is 'd1' and for the braking operation the duty ratio is 'd2'. GIVEN DATA:- The other parameters of the  electric vehicle is given below,        Motor and…

ANSWER:- 1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type.. Mapped and Dynamic subsystem of Electric Motor/GeneratoR: Mapped:-   Mapped Model::-  The mapped model is one type where the data points are pre_assigned in lookup tables.  The…

ANSWER:-  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. We have to change the model advisor tool on this given data. STEP:1 CHANGE THE MODEL Into EV IN DRIVETRAIN CONFIGURATION:- STEP:2 HERE WE…

Aim :- Traffic Jam Assistant Feature;- Objective :- This model must be developed in MATLAB Simulink as per MBD guidelines according to the requirements given. Tag the requirements to the Simulink model, Requirements 1 & Requirement 2 are tagged into their corresponding subsystems. Creation of Simulink Data Dictionary…

Aim :- Develop a MATLAB Simulink Model for Adaptive Cruise Control feature used in Automotive Vehicle Objective:- To develop a Adaptive Cruise Control feature as per the Requirement Document using MATLAB Simulink. While Developing the Adaptive Cruise Control Simulink Model, we have follow all the MBD related processes…

MINI-PROJECT: General Overview: Identifying the direction of the vehicle is one of the important & diverse features in Autonomous driving & Advanced Driver Assistance Features. This particular sub-feature of identifying the direction of vehicle is basically identifying the direction the vehicle is taking based…

Make a Simulink chart for the “Gear shift” logic as per below conditions:         Speed Range(kmph)        Gear                0 to 15           …
