Week-7 Challenge: DC Motor Control

Part A: 1. Search and list out the total weight of various types of aircrafts.  Types of aircraft: There are a number of ways to identify aircraft by type. The primary distinction is between those that are lighter than air and those that are heavier than air. Lighter-than-air: Aircraft such as balloons, nonrigid airships (blimps),…

1. For a defined driving cycle, calculate the energy required for braking. 2. Why electric motor can’t develop braking torque at high speed similar to starting? How electric and mechanical brakes are coordinated?  Electric mototr have high high  torque producing capability at low starting torques. But as…

1. Run MATLAB demo ‘Speed control of a DC motor using BJT H-bridge’. Modify the model such that armature current doesn’t shoot up when motor changes direction from forward to reverse. To know more about the Speed control of a DC motor using BJT H-bridge, we need to know about the components used in the…

1.  Which types of power converter circuits are employed in electric and hybrid electric vehicle?    This technology deals with processing and controlling the flow of electrical energy in order to supply voltages and currents in a form that is optimally suited for the instruments.  As shown in…

1. What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Mapped models: Mapped models are used when the behavior of a particular models that is not of our interest and can be modeled with predefined values from look up tables.   Mapped model example:…

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. Install the ADVISOR tool and open it from the comand window and open the required car model from load file option According to the requirement cargo mass…

Aim: To develop Highway Assistant Lane Changing Assistant algorithm. Abstract: The Highway Assistant supports the driver and takes over the longitudinal and lateral guidance of the vehicle in monotonous driving situations on highways. The partially automated function can automatically start, accelerate, brake as well as…

Aim: To develop a model that represents Traffic Jam Assistant Feature. Abstract: Traffic Jam Assistant is one of the most common feature in Advanced Driver Assistance System. Traffic Jam Assistant helps the driver arrive more relaxed at their destination, even in dense traffic or in traffic jams. As a partially automated…

Aim: To Develope a model to represent Adaptive Cruise Control. Abstract:  Adaptive Cruise Control Feature for passenger cars allows the host vehicle to adapt to the speed in line with the flow of traffic. Driving in heavy traffic or keeping a safe distance to the preceding vehicle calls for a high level of concentration.…

Aim: To develope a model to show vehicle direction determination. Abstract: 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…

Control logic of a washing machine A washing machine is a machine to was clothes, sheets and laundry. The process involves soaking, rinsing, washing and drying. Parameters: Soaking = 200 sec Washing = 100 sec Rinsing = 20 sec Drying = 50 sec Simulink model: Stateflow chart: When water supply not available: Blocks used:…

Aim: To make a simulink model od Dooebell using solenoid block. To use a thermistor to sense the temperature of a heater and turn on or off the fan. Condition for doorbell: Create a situation where the switch is closed for 2 seconds and then released. Observe the physical movement of the plunger. Condition for thermistor:…

AIM: To read and calculate specific heat, enthalpy and entropy for all the species from the given NASA thermodynamic data file. OBJECTIVE:  To write a function that extracts the 14 co-efficients and calculates the enthalpy, entropy and specific heat To calculate the molecular weight of each species and display…

Genetic Algorithm: Aim: To write a code in MATLAB to optimize the stalagmite function and to find the global maxima of the function. Given:  `f1,x=[sin(5.1pix+0.5)]^6` `f1,y=[sin(5.1piy+0.5)]^6` `f2,x=exp[-4ln(2)(x-0.0667)^2/0.64]` `f2,y=exp[-4ln(2)(y-0.0667)^2/0.064]` `f(x,y)=f1,x*f2,x*f1,y*f2,y` To use this formula…

Aim: To solve the program that solves ODE and create an output for simple pendulum. Given data: `d^2/dt + b/m d theta/dt + g/L sin theta=0` here,  g = gravity in m/s2 L = length of the pendulum in m m = mass of the ball in kg b=damping coefficient To use, L=1 metre m=1 kg b=0.05 g=9.81 m/s2 angular velocity =…

Aim : To solve and plot otto cycle. Errors Faced: Error1: Error2: Error3:   Explanation of code: %otto cycle Line 1 - 3: Clear, close commands for clearing the command window and workspace. Line 6 - 8: Input values of gamma and temperature at point 3. Line 10 - 12: Values of state variables at state point 1.…
