In this paper, the pole placement controller based on the Robust Internal-loop Compensator(RIC) structure, which has inherent structural equivalence to disturbance observer, is proposed to control a linear positioning system. This controller has the advantage to easily select controller gains by using pole placement without loss of that of original RIC structure. The principal is to construct t...

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 the control theory one attempts to find a controller that provides the best possible performance with respect to some given measures of performance. There are many sorts of controllers e.g. a typical PID controller, LQR controller, Fuzzy controller etc. In the paper will be introduced polynomial controller with novel tuning method which is based on the special pole placement encoding scheme ...

<span>The requirements <span>for the network are increasing by expanding and spreading Internet. The Previous techniques of do not meet modern needs, thus, a new technical presents software-defined networking (SDN). SDN recognizes as promising model that separates control plane (traffic routing topology) from data (network architecture layers). has some features find in single contr...

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...

Network-on-chip based manycore systems with multiple memory controllers on a chip are gaining prevalence. Among other research considerations, placing an increasing number of cores on a chip creates a type of resource access asymmetries that didn’t exist before. A common assumption of uniform or hierarchical memory controller access no longer holds. In this paper, we report on our experience wi...

Software defined network is a new computer network architecture who separates controller and data layer in network devices such as switches and routers. By the emerge of software defined networks, a class of location problems, called controller placement problem, has attracted much more research attention. The task in the problem is to simultaneously find optimal number and location of controll...
