minreal

Control Systems

Minimal realization via pole-zero cancellation. Removes common poles and zeros from a transfer function within tolerance 1e-6. Returns simplified TF.

Syntax

minreal(sys)

H = tf([1, 1], [1, 2, 1]); Hmin = minreal(H) % cancels (s+1)/(s+1)^2 = 1/(s+1)

H = tf([1, -1, -2], [1, 0, -4]); minreal(H)
