Control Systems Engineering [EXP-57621]

(UFSS Case Study) As a final example, let us use MATLAB to do the UFSS Case Study in the text (Johnson, 1980). We introduce table lookup to find the rise time. Using the interp1(y, t, y1)command,weset up a table of values ofamplitude,y, and time,t, from the step response and look for the value of time for which the amplitude is y1= 0.1 and 0.9.We also generate time response data over a defined range of time using t=a: b: c followed by [y, t]=step(G, t). Here G is an LTI transfer-function object and t is the range for the time axis, where a is the initial time, b is the time step size, and c is the final time; y is the output.

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

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, Kp, Kv, and Ka. Let us look at Example 13.9 in the text. You will input T, the sampling interval

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
