MATLAB: How to set Values to Simulink Block from the Workspace

blockMATLABsimulinkvaluesworkspace

I want to send PID Values to Simulink Model from my file.m
I have tried this way but I got an error which I dont understand what it means…
 PID_Values = set_param('Simulink_Model/PID Controller','PID Controller','1','1','1'); 
 ERROR: PID 1dof block (mask) does not have a parameter named 'PID Controller'
or
 P_Value = set_param('Simulink_Model/PID Controller','PID Controller','1'); 
 I_Value = set_param('Simulink_Model/PID Controller','PID Controller','1');
 D_Value = set_param('Simulink_Model/PID Controller','PID Controller','1');
 ERROR: PID 1dof block (mask) does not have a parameter named 'PID Controller'

Best Answer

To get the list of parameters associated with 'PID Controller' block, I would use the below command :
allParams = get_param('Simulink_Model/PID Controller', 'DialogParameters');
If you are looking to find any particular parameter value, let's say the Proportional Gain :
P_Gain_Val = get_param('Simulink_Model/PID Controller', 'P');
For setting values , (P = 10, I = 2, D = 0.1)
set_param('Simulink_Model/PID Controller', 'P', '10', 'I', '2', 'D', '0.1'); % No output argument
