Output function control in general state space systems containing the first derivative of the input vector

Abstract
In this paper, linear control systems are considered whose state equation is of the form Edx/ dt = AX+ Bo u + B1 where A, B,o and and B1 constant matrices, while E is a square matrix that may be singular and time-varying. The problem to be solved is if the output of the system is a prescribed function of find inputs that generate the desired output. The results are readily applicable to ‘ output zeroing problems ’ for example to the calculation of the finite and infinite zeros and the corresponding Zero-directions of regular and singular time-invariant systems. The assumption that E may have time-varying elements makes the method developed in tho paper applicable to certain perturbation problems.
