Week 3 - Solving second order ODEs

  OBJECTIVES: To Create a detailed MATLAB model of an electric rickshaw (three wheel passenger vehicle) as per details below:  Rear wheels driven by PM brushed type motor Assume efficiency points of motor controller and motor To Make an excel sheet of all input and assumed data  Results: For any three standard…

1) Search and list out the total weight of various types of aircraft. The total weight of aircraft is found by summing up a different type of weight in an airplane. The different types of weight in aircraft are 1) Standard Empty Weight 2) Zero Fuel Weight 3) Operating Empty weight 4) Payload 5) maximum take off weight…

1) For a defined driving cycle, calculate the energy required for braking.   The drive cycle is created in excel with time, velocity is KMPH and m/s and energy is calculated and we used chart option and we got the drive cycle with respective time and velocity in KMPH. Now we have to find the braking energy so now we choosed…

Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’ The Bipolar junction Transistor(BJT) when used for power switching application, operates as an IGBT when it is conducting, a forward voltage Vf is developed between collector and emitter. Therefore, the IGBT block can be used…

1) Which types of power converter circuits are employed in an electric and hybrid electric vehicles? There are dour types of power converter circuits used inan  electric and hybrid electric vehicle are: 1) AC - DC converter( Rectifier) 2) DC - AC converter(Inverter) 3) DC-DC converter ( Chopper)      (i)…

1) What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?   Mapped model:         This type of model uses a set of steady state lookup tabel to detemine engine performnce. This model is used for analysis and desiging purpose which…

In this case, ev vehicle type is chosen and the EV_defaults_in file is also chosen. Then cargo mass is changed to 500kg and all other conditions remain the same.        In the next step, the CYC_FTP drive cycle is chosen and a number of cycles is entered as 1 ie : 17.8 km From the output result table,…

AIM: To write a code for compatibility check          To write a code for data visualizer          To write a code for calculating the area under PV graph, power, and specific fuel consumption   case1; compatibility check  we have used 'try' block command for…

1. What does popt and pcov mean? (Watch the video to get some context) popt is an array where all the coefficient of the equation is generated with respect to the polynomial degree.  pcov is a 2D array that consists of the covariance of popt. Covariance gives the relation between two values, so here pcov gives the…

AIM To create a simple pendulum oscillation motion using a intode command (from scipy module) to solve a second-order differential equation.   Formulae used `(d^2 θ)/〖dt〗^2 +b/m dθ/dt+g/l sinθ=0`   EXPLANATION NOTE: we have to download the scipy module to perform this challenge. Initially, we…

Aim To plot a PV graph for the otto cycle.   Formulae used  `V_S = π/4 × d^2 × l`-Swept volume  `V_C = V_S /((c r − 1 ))`-Clearance volume `P_2 = P_1 × ( ( c r )^γ )`  `c = P _1 × ( ( V 1 ) ^γ )`    `P _3 = P _2 × ( (T _3 )/ (T _2 ))` `P _4…

AIM To conduct a system-level analysis in BAJA ATV MODEL 1-Baja ATV without a dashboard, without a  lookup table  SIGNAL BUILDER -in this particular model we have used this signal builder block to produce our prime inputs such as THROTTLE and BRAKE. verterThrottle input is generally given to the generic engine…

AIM 1. TO APPLY CONTROL LOGIC IN WASHING MACHINE PROCESS USING CHART BLOCK 2. TO MAKE A GEAR SHIFT LOGIC USING CHART BLOCK IN SIMULINK   WASHING MACHINE Washing machine runs by a set of process[states] chain   soaking  washing rinsing drying  we need to apply a simple state control logic to execute…
