I have a linear equation y = -0.0563x + 0.7831 I am trying to find Laplace of this equation in Y(s)/ X(s) format. I do not know how to achieve it? Please help me. This equation describes the performance of a motor... torque vs angular speed (motor characteristic curve approximated to a linear equation for simplicity). It is important to have solution in Y(s)/X(s) format. I need to do a step and impulse response analysis on the system in matlab. Please give me some hints.
