Project-1: Modelling an electric Car with Li-ion battery

Create a MATLAB model of electric car which uses lithium ion battery and suitable motor. Choose suitable blocks from Simscape or Powertrain block set. Implement the vehicle speed control using PI controller and generate brake and accelerator commands. Avoid using readymade driver block for speed control.

Prepare a report about your model including following:

Objectives, System level configurations, Model parameters, Results, Conclusion.

SYSTEM LEVEL CONFIGURATION:

 

PID CONTROLLER:

Reference velocity is connected to the product in (+,-) is connected to the pid controller is connnectedd tot the one upon a acceleration and other one is deaccceleration and both are connected to the transfer ffunction abs,and the output is accelerration cmd and deacceleration cmd

SUM:

sum is connected to the input and output
