C2d in matlab
WebOur first step in designing a digital controller is to convert the above continuous state-space equations to a discrete form. We will accomplish this employing the MATLAB function c2d. This function requires that we … WebThe commands c2d, d2c, and d2d perform continuous to discrete, discrete to continuous, and discrete to discrete (resampling) conversions, respectively. sysd = c2d (sysc,Ts) % Discretization w/ sample period Ts …
