Implementation of Shortest Control Path Finder for a Hybrid Electrical Vehicle Control using Matlab Simulink

Implementation of  Shortest Control Path Finder for a  Hybrid Electrical Vehicle Control  using Matlab Simulink

This example shows how to find the shortest control path for a hybrid electrical vehicle using Signal Tracing Command-line API. In this model, a Hybrid Electrical Vehicle drives on a slope and the initial speed is 0 m/s. Set the target speed to 30 m/s. In Driver, a PID control compares the actual speed with the target speed and sends a command to increase or decrease speed to the power demand estimation module.  Power demand estimation converts to the desired power, and the power is primarily provided by the electrical motor. If electrical motor is unable to provide enough torque, then the engine and provides additional torque. In Vehicle Dynamic, road resistance including rolling resistance and gravity resistance as well as the aero drag are calculated. The actual speed of the vehicle is constantly returned to Driver through the feedback loop until the vehicle reaches the target speed. 1) Trace All Sources that Control the Actual Speed 2)Obtain the Trace Graph 3) Find the Shortest Path from Trace graph 4) Simulation : Shortest Control Path for a Hybrid Electrical Vehicle Click here to download the demo files: https://drive.google.com/file/d/1NU4jML0j8DzMxP0Z43Q9okayTCyolLPf/view?usp=sharing https://drive.google.com/file/d/1XRuV44_9TzpHn6G2qJ0rOnLEL29yhai4/view?usp=sharing Kindly Subscribe My YouTube Channel...

Design & Analysis of Indoor Digital TV Rx & Broadcasting System using Discone Antenna

Design & Analysis of Indoor Digital TV Rx & Broadcasting System using Discone Antenna

This example shows how to design and implement a discone antenna for indoor use in digital TV receiving and transmitting systems. 

Discone antennas are wide bandwidth and omnidirectional radiation antennas that are widely used in VHF and UHF broadcasting systems. 

The described antenna provides matched bandwidth, below -10 dB of return loss, between 460 MHz and 2.3 GHz, and provides omnidirectional radiation pattern within the considered TV band, from 470 MHz to 862 MHz. 

Matlab Script:

Design and Control of Dual Active Bridge Converter For Grid-Tied Inverters

Design and Control of Dual Active Bridge Converter For Grid-Tied Inverters

This example shows standard control with 50% duty cycle on both bridges and phase shifting to control output voltage. It works well with a variable step solver as the PWM generator is designed for continuous time domains. Adrián Casado (2022). https://in.mathworks.com/matlabcentral/fileexchange/63442-dual-pv-generator-mppt-boost-h-bridge-cascaded-inverter A dual active bridge is a bidirectional DC-DC converter with identical primary and secondary side full-bridges, a high frequency transformer, an energy transfer inductor and DC-link capacitors. Each switch is on for 50% of its respective switching period. The switch pairs in the two bridges all have the same switching period but are operated such that between each bridge a phase shift is introduced that varies based on the modulation derived from feedback measurements. An output voltage error signal is generated based on a set point value and this is fed through a digital PI regulator to generate the phase shift ratio for the PWM modulator.
