Control Systems Engineering [EXP-57621]

Wecan useMATLAB’s commanddcgain(Gz)to find steadystate errors. The command evaluates the dc gain of Gz, a digital LTI transfer function object, by evaluating Gz at z = 1. We use the dc gain to evaluate, $K_{p}$ , $K_{\nu }$ , and $K_{a}$ . Let us look at Example 13.9 in the text. You will input T, the sampling interval, through the keyboard to test stability.

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)

We now use the root locus to find the gain for stability. First, we create a digital LTI transfer-function object forG(z) = N(z)/D(z), with an unspecified sampling interval. The LTI object is created using tf(numgz, dengz,[ ]), where numgz represents N(z), dengz represents D(z), and [ ] indicates

We also can use MATLAB to convert G(z) to G(s) when G(s) is not in cascade with a z.o.h. First, we create a sampled LTI transfer function, as discussed in ch13p3. The command F=d2c(H,’zoh’) transforms H(z) to F(s) in cascade with a z. o.h., where H(z) = ((z – 1)/z)z{F(s)/s}. If we consider F(s) =

Creating Digital Transfer Functions Directly Vector Method, Polynomial Form A digital transfer function can be expressed as a numerator polynomial divided by a denominator polynomial, that is, F(z) = N(z)/D(z). The numerator, N(z), is represented by a vector, numf, that contains the coefficients

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

We can design observer gains using the command l = acker (A’ ,C’ , poles)’ without transforming to observer canonical form. Let us look at Example 12.8 in the text.

We can test observability using the MATLAB command Om=obsv(A , C)to find the observability matrix given the system matrix (A) and the output matrix (C). This command is followed by rank (Om) to test the rank of the observability matrix (Om). Let us apply the commands to Example 12.6.
