AIM: To create a detailed MATLAB model of an electric Rickshaw. THOERY: Electric rickshaws (also known as electric tuk-tuks or e-rickshaws or toto or e-tricycles) have been becoming more popular in some cities since 2008 as an alternative to auto rickshaws and pulled rickshaws because of their low fuel cost, and less human…

AIM: To create an Electric Vehicle Model using Simulink and Matlab. THEORY: An electric vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with…

AIM: To learn about braking in the EVs using Matlab. THEORY: REGENERATIVE BRAKING: Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction…

AIM: To modify a Matlab demo DC model such that armature current doesn’t shoot up when motor changes direction from forward to reverse. To compare the Four-Quadrant Chopper DC Drive (DC7) block with H-bridge model. To make a suitable EV model using DC7 block and make result report. THEORY: FOUR QUADRANT CHOPPER:…

  AIM: To learn about types of power converter circuits used in electric and hybrid electric vehicle, to solve a problem related to EV vehicle and to explain a blog about authors perspective. THEORY: The task of a power converter is to process and control the flow of electric energy by supplying voltages and currents…

AIM: To study HEV (Hybrid Electric Vehicle) and EV (Electric Vehicle) from Reference application projects in Simulink. THEORY: HEV (HYBRID ELECTRIC VEHICLE): A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system…

AIM: To perform simulation on various vehicle modules with different conditions using ADVISOR Tool. THEORY: ADVISOR, NREL’s ADvanced VehIcle SimulatOR, is a set of model, data, and script text files for use with Matlab and Simulink.  It is designed for rapid analysis of the performance and fuel economy of conventional,…

AIM: To carry out a system level simulation of an All-Terrain Vehicle (ATV). THEORY: ALL-TERRAIN VEHICLE(ATV): An all-terrain vehicle (ATV), also known as a quad, as defined by the American National Standards Institute (ANSI) is a vehicle that travels on low-pressure tires, with a seat that is…

AIM: To Implement control logic of a “washing machine” using Stateflow and to Make a Simulink chart for the “Gear shift” logic. THEORY: WASHING MACHINE: A washing machine (laundry machine, clothes washer, or washer) is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed…

AIM: To make a Simulink Model of Door Bell using solenoid block. To make a Simulink Model Using a thermistor to sense the temperature of a heater & turn on or turn off the fan.  SOLENOID: A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound…

AIM: To plot a function using basic Simulink blocks and to run and study  a Simulink example ‘Suspension System Comparison’. SUSPENSION: Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension…

AIM: To write a code in MATLAB for parsing the NASA Thermodynamic data file and using this extracted data to calculate specific data, enthalpy, entropy and molecular mass of each species.   FILE PARSING: Parsing a file means reading in a data stream of some sort and building an in memory model of the semantic content…

AIM: To write a code in MATLAB to optimise the stalagmite function and find the global maxima of the function.   STALAGMITE: A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings.…

AIM: To write a code for to fit a linear and cubic polynomial for the Cp data and to show splitwise method using Matlab.   CURVE FIT: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve…

AIM: To write a Matlab program to solve an Ordinary Differential Equation (ODE) that represents equation of motion of a simple pendulum with damping.
