Question: Use recursive least squares to estimate the transfer function for the LTI model given in Example 10-2 using the impulse response data y(k). Verify that
Use recursive least squares to estimate the transfer function for the LTI model given in Example 10-2 using the impulse response data y(k). Verify that the poles of this transfer function match the eigenvalues of the system matrix identified in Example 10.2.
Example 10.2
Consider the following impulse response data for a SISO discrete-time LTI system with
a sampling time of T = 0.01 s. The output is measured at the sampling time instants
t = 0, 0.01, 0.02, c, 0.08, as shown in Fig. 10-2.
