pid control block for one axis calibration inside a blackbox in matlab

main.m
% Define the PID controller parameters
Kp = 1;
Ki = 0.1;
Kd = 0.05;

% Create the PID controller object
pid_controller = pid(Kp, Ki, Kd);

% Set the desired setpoint for the calibration axis
setpoint = 0;

% Create the input signal to the PID block
input_signal = ... % Define your input signal here

% Create the output signal from the PID block
output_signal = zeros(size(input_signal));

% Loop through each sample in the input signal
for i = 1:length(input_signal)
    % Get the current error signal
    error_signal = setpoint - input_signal(i);
    
    % Update the output signal from the PID controller
    output_signal(i) = pid_controller(error_signal);
