in this paper the active vibration control of a four-story shear frame instrumented with piezoelectric actuators is presented. the piezoelectric actuators are hosted on the columns in two manners and the produced controlling forces by actuators are considered in the equation of motion. the smart structure modeling and control design is carried out using matlab software in state space form. subs...

In this paper, we have presented a simple method in order to solve the pole placement problem of linear output feedback systems with state space models. Pole placement is a control method assigned to arbitrary closed loop poles by state or output feedback. In linear systems, poles have influence on stability, system response, transient response, and band width. Pole placement methods are used i...

s-Fixed controllers can become even unstable, with large changes in system parameters. This problem can be avoided using robust control and adaptive control design techniques. To obtain robust performance, it is desirable that the closed loop poles of the perturbed structure remain at prespecified locations for a range of system parameters. In the present study, the controllers based on adaptiv...

Guaranteed dominant pole placement problem has already been considered in the literature (Journal of Process Control 19(2009):349–352). For the systems that are higher-order or have dead-time, pole placement procedure with PID controllers via modified Nyquist plot and root-locus has been proposed. Based on this idea, the dominant pole placement problem with discrete-PID controllers in zdomain i...

We formulate and solve a pole placement problem by state feedback for overdetermined 2D systems modeled commutative operator vessels. In this setting, the transfer function of system is given meromorphic bundle map between two holomorphic vector bundles finite rank over normalization projective plane algebraic curve. The obstruction solution an existence certain on input bundle. Reducing to 1D ...
