Find matlab code for LQR function?

Answer 1

In MATLAB, you can use the built-in lqr function to compute the Linear Quadratic Regulator (LQR) gain matrix. The basic syntax is K = lqr(A, B, Q, R), where A is the state matrix, B is the input matrix, Q is the state weighting matrix, and R is the input weighting matrix. Ensure you define these matrices appropriately based on your system dynamics before calling the function. For example:

A = [...];  % Define your A matrix
B = [...];  % Define your B matrix
Q = eye(size(A));  % State weighting
R = 1;  % Input weighting
K = lqr(A, B, Q, R);
