2.Single-input,single-output (SISO)n,-th and n2-th order systems are described by:System I:dx=A1x1+B,u,y1=Cix1dtSystem II:2 A2X2 B2u2,y2=C2X2dtConsider series and parallel combinations of the two systems as described below.For theseries combined system,the input is u1 and the output is y2.In addition,the“input'”of“System II'”is the output of“System I'”,i.e.,u2=y1.For the parallel system,the input isu u uz and the output is y y1 y2.System ISystem IlSystem ISystem IISeries CombinationParallel CombinationDetermine the controllability and observability of the series and parallel combinations ofthe following two systems:A1=[2-3B1=[,G1=[21,D1=0A2=[3B2=[H,C2=[111],D2=0Obtain transfer functions for the combinations.
