Question

Create matlab simulink model for dc-dc buck converter with screenshot.
Note: provide matlab code for the output of dc-dc buck converter if possible.

Answer 1

Beginning from here

% you have to update the following

% blocks:

%

% * Host_Read_12M_COM9_CL/Serial Configuration

% * Host_Read_12M_COM9_CL/Serial Receive

% * Host_Read_12M_COM9_CL/Serial Send/Serial Send

%

%% Run the Example

%

% * Open the target model <matlab:open_system('DCDC_Buck.slx')

% DCDC_Buck.slx> and generate code by typing Ctrl+B. Follow the build

% process by opening the diagnostic viewer with the link provided at the

% bottom of the model canvas. Once the code is loaded on the board, a blue

% LED blinks at a period of 1 second on the LaunchPad indicating that the

% code is properly running.

%

% * Open the host model <matlab:open_system('Host_Read_12M_COM9.slx')

% Host_Read_12M_COM9.slx>. Make sure that your COM port is properly

% configured following the model configuration instructions. Click on the

% play button to run the model.

%

%% Monitor Signals

%

% While the host model is running, the following signals can be monitored

% on the scope:

%

% # *I_FB Current*: The current flowing in the load resistors. Raw values

% are displayed to allow real-time logging. *4095 counts > 3.3A*

% # *V_FB Voltage*: The measured output voltage of the system. *4095 counts

% > 6.8V*

%

%% Tune Parameters

%

% While the host model is running, you can tune parameters that will be

% sent to the hardware using the following *dashboard blocks*:

%

% # *Voltage Request*: Change the output voltage demand. This parameter is

% the main request for the control loop. The controller algorithm will

% compare this value with the measured output voltage and adjust the PWM

% duty cycle to towards achieving that output voltage.

% # *Active load*: Turn on and off the active load present on the hardware.

% This parameter allows you to add an extra load resistor to study the

% effect of abrupt changes in the load circuit.

% # *P Gain*: Change the proportional gain of the controller algorithm. You

% can change this parameter to study the robustness of the controller.

% Aggressive changes may lead to instability of the controller, apply

% changes wisely.

% # *I Gain*: Change the integral gain of the controller algorithm. You can

% change this parameter to study the robustness of the controller.

% Aggressive changes may lead to instability of the controller, apply

% changes wisely.
