Arbitrary adaptive pole placement for linear multivariable systems. (English) Zbl 0534.93026
The authors present a method for assigning all the closed-loop poles of a linear time-invariant multivariable system. The approach is applicable to the complete class of continuous-time multivariable systems characterized by proper transfer matrices. Required a priori information for implementation consists of only the system controllability indexes and an upper bound on the observability indexes. In the presentation, both the continuous-time and the discrete-time case are treated almost in parallel. At first, a fixed control strategy is formulated which can be interpreted as linear state feedback via asymptotic state estimation. Then the adaptive control strategy is developed, which may be implemented by a state space realization of order (dim. of input vector)\(\times\)(upper bound of the observability indexes). Local stability results are mentioned. In the last section, three instructive examples are treated in detail.
