Use LU Decomposition to find the coefficients. input should be a set of points (x,y) and output the coefficients (ao, ay, and az), the coefficient of determination (r), and the correlation coefficient (r). Please test your function on the data below and plot the results: X Y -10...
PID controller MATLAB 5. Apply a PID controller on the closed loop system and write a MatLab scrip that will allow you to change the values of P, I, and D coefficients and plot the effects of this values on the step response of the system. Show all posible forms obtained when changing the values of the PID controller. When is the system damped, overdamped, etc. Chose values of P starting from 0 to any value you want. Do the...
