Control Systems Engineering [EXP-57621]

Let us now use MATLAB to design a digital lead compensator. The s-plane design was performed in Example 9.6. Here we convert the design to the zplane and run a digital simulation of the step response. Conversion of the s-plane lead compensator, Gc(s)=numgcs/dengcs, to the z-plane compensator, Gc(z)=numgcz/ dengcz, is accomplished using the Gcz=c2d (numgcs, dengcs, T, ‘ tustin’) command to perform a Tustin transformation, where T=sampling interval, which for this example is 1/300. This exercise solves Example 13.12 using MATLAB.

We also can use MATLAB to convert G(s) to G(z) when G(s) is not in cascade with a z.o.h. The command H=c2d(F , T , ‘zoh’)transforms F(s) in cascade with a z.o.h. to H(z), where H(z) = ((z – 1)/z)*z{F(s)/s}. If we let F(s) = sG(s), the command solves for H(z), where H(z) = ((z – 1)/z)*z{G(s)}. Hence
