Hi
I have system (NOT transfer function) that gives vector numbers. Also, I have specific desire output. I would like to add PID controller as a control to reduce the error between the desire and output based on specific variable (d). Can you please help me with this situation
For example,
A=[0 3 12.5 12.8 11.8 12.3 11.9 12]; % practical data
d=1; % variable
OUT=A*d; % output
Vdesire=12; % desire outputHi

I have a Simulink model that uses variables set in Matlab code. However it keeps giving me the same error.
I have this function
function y = tclabsim(t, x0, u, p)
% Ensure input sizes match
if length(t) ~= length(u)
error(‘Time vector t and input profile u must have the same length.’);
end

% Extract parameters from p
U = p(1); % Heat transfer coefficient
alpha = p(2); % Ambient heat loss parameter
tau = p(3); % Time constant

% Initial conditions
x0_T = x0; % Initial temperature

% Ensure t and u are column vectors
t = t(:);
u = u(:);

% Create input matrices
inputMatrix = [t, u];
U_matrix = [0, U];
alpha_matrix = [0, alpha];
tau_matrix = [0, tau];
x0_T_matrix = [0, x0_T];

% Set simulation stop time
stopTime = t(end);

% Assign all required variables to base workspace
assignin(‘base’, ‘x0_T’, x0_T_matrix);
assignin(‘base’, ‘U’, U_matrix);
assignin(‘base’, ‘alpha’, alpha_matrix);
assignin(‘base’, ‘tau’, tau_matrix);
assignin(‘base’, ‘inputMatrix’, inputMatrix);

% Run the Simulink model
simOut = sim(‘SingleHeaterTCLab_1.slx’, ‘SrcWorkspace’, ‘current’, …
‘StopTime’, num2str(stopTime));

% Extract the output from the simulation
y = simOut.Ts; % Sensor temperature output
end
And I call the function like this
% Time vector (0 to 1000 seconds with 1-second steps)
t = (0:999)’; % Make sure t is a column vector

% Initial temperature (20°C)
x0 = 20;

% Heater input (step response: 50% heater power after 100s)
u = zeros(size(t));
u(t >= 100) = 50;

% Parameters [U, alpha, tau]
p = [0.01, 0.01, 200]; % Example values for U, alpha, tau

% Simulate the system
y = tclabsim(t, x0, u, p);
However, every time I try to run it gives the same error.

I have tried to load them as simple double and I have also tried a matrix with t on the first column and the same value in every line of the second column. They also gave the same error.
The block in Simulink has these properties. And I have also tried to change the sample time to -1.

This is the entire simulink if it helps.

How can I fix it?

I’m working on a MATLAB project where I need to analyze and plot the relative difference in coverage area for different QAM orders and semi-angles (ϕ_1/2) for a wireless communication simulation. I’ve encountered two persistent errors:
Error using xticks (line 33)
Value must be a numeric vector whose values increase.
Error in untitled11 (line 84)
xticks(QAM_order); % Ensure QAM_order is numeric and sorted
and One more thing is the legend has multiples 15, 30, 45 as shown in the below image

Expected Outcome:
Correct x-axis ticks: The x-axis should display the QAM orders {16,32,64,128,256,512,1024}.
Unique legend entries: Each angle (ϕ1/2 =15 ∘ ,30 ∘ ,45 ∘) should appear exactly once in the legend.

Dear colleagues,
I need to perform a regression. The input data is shown in Figure 1 and is also attached as an MS Excel file.
Figure 1 (Figures are shown in the end of the letter.
The equation is z = a*x^m/(y+c)^n.
The parameters of the fit are shown in Figure 2 and are also attached.
Figure 2

The output data is shown in Figure 3.
Figure 3
The individual differences in percentage are shown in Figure 4.
Figure 4
I know that by using a weighted matrix, it is possible to decrease some differences (priority zones) at the expense of increasing others. However, in this case, my goal is to estimate the minimal possible error (one border value) for all of the values. For example, in the first fit, the maximum difference is 93%. It is easy to decrease it by applying individual weight coefficients, but of course, somewhere, the difference will increase. Therefore, the question is: what method can be used to find the minimal possible difference? If this for example is 18%, it means that everywhere the difference will be smaller, and it is likely that there is no 0 % anymore. Example by hand (not real) is given in Figure 5.
Figure 5
And if we try to decrease the difference at the point with an 18% difference, this will lead to an increase in the difference somewhere above 18%. Also, if in the first fit I have a 0% or 1% difference at a given point, in the second fit, the difference at this point is likely to be close (but smaller) to 18%. And one more thing – if there is a way for doing the whole procedure, is it possible to use curve fitter app or need to use a code?Dear colleagues,
