How can I set Values to Simulink Block from my Workspace?

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'

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

error is saying that the specific block you are using does not have parameter 'PID Controller'.

select the block, then type get_param in command window,

all parameters of that block (object) will be displayed, now use set_param to change any parameter value

[Bob]

 P_Value_get = get_param('Simulink_Model/PID Controller','PID Controller','P'); 
 I_Value_get = get_param('Simulink_Model/PID Controller','PID Controller','I');
 D_Value_get = get_param('Simulink_Model/PID Controller','PID Controller','D');

 P=10;
 I=100;
 D=1000;

 P_Value_Set = set_param('Simulink_Model/PID Controller','PID Controller','P'); 
 I_Value_Set = set_param('Simulink_Model/PID Controller','PID Controller','I');
 D_Value_Set = set_param('Simulink_Model/PID Controller','PID Controller','D');

Again error

You are not using get_param and set_param in a proper way. Please type

   help get_param
   help set_param

in matlab command prompt to see the intended usage.
