 a linear time-invariant
 A linear time-invariant discrete system with a single bounded control input is considered. The system considered is described by a linear time-invariant recurrence equation in which the number of inputs equals the number of states. We consider an optimal stabilization problem for an uncertain system described as a linear time-invariant plant closed by an uncertain feedback which is a conic nonlinearity. We consider a linear time-invariant finite-dimensional system x=Ax+Bu with multi-inputu, in which the matricesA andB are in canonical controller form. Numerical examples involving the modeling of a linear time-invariant fourth-order system by a second-order model and the design of quarter-wave transmission-line transformers illustrate the results. 更多
 The mothod designing a constant controller of a linear time-invariant multivariable system is presented in this paper. One line in the feedback control matrix is used for the assignment of the poles of the closed-loop system. Other lines in the feedback control matrix are used for minimizing the sensitivity of the poles of the system to the purturbations.A performance index is obtained, which is defined from the variation of the poles of the closed-loop system in the complex plane. The numerical examples... The mothod designing a constant controller of a linear time-invariant multivariable system is presented in this paper.

In this paper, a simplified algorithm to solve the problem of pole-assignment in a linear time-invariant multivariable system is presented. Since this simplified algorithm requires no computation of the characteristic polynomial of the controlled system, it makes the practical calculation convenient.Since the design of observer can be reduced to a pole-assignmemt problem, this algorithm also simplifies the procedure of observer design. 本文提出极点配置问题的一个简化算法。该算法不需要计算控制系统的特征多项式,因此给实际计算带来方便。由于观测器的设计可化为极点配置问题,该算法也简化了观测器的设计。 In this paper, a linear time invariant system is considered as a linear transformation in the finite dimensional solution space of the system, and the designing methods of its robust regulator are discussed in a general sense.
