MATLAB: PID BLOCK IN SIMULINK

simulink

I have worked out that my PID controller is

Gc = 4.2(1 + 1/1.57s + 0.39s)

I want to put this into a block on simulink but the PID controller block in simulink is in a weird form. Does anyone know how to get around this. Thanks.

In the Simulink PID block, In the form field, change the form from parallel to ideal and set the value of filter coefficient N to be quite high (say 200). Then parameters P, I, and D can be used from your current transfer function.

2 options

1)you can use the shipping PID controller black and make the value of N very high.

2) Create you own PID block with pure derivative

Keep in mind that any real measurement is always noisy, and that differentiating noise is always bad.

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
