The root-locus method is a well-known tool for control system analysis and design. It is an important topic in introductory undergraduate engineering control disciplines. In this paper we present the analysis of a transfer function using root locus method. Through analysis of transfer function we check the effect of gain on poles and zeros.

Due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. This paper employs Modified Petri Nets (MPN) to model theses subsystems and makes it simple to analyze them. In this method, first, the continuous transfer function is converted to a discrete transfer function and then, by MPN, system is modeled and analyzed. All...

The problem of stabilizing a linear control system leads to several important considerations. In particular, there are certain basic requirements which need to satisfied in any practical feedback system [6, 7, 11, 18]. First, the closed-loop system needs to be internally stable, i.e., the transfer function between any two points in the loop should be stable. Internal stability guarantees that a...

By revealing the deficiency of existing internal model control (IMC) based methods for load disturbance rejection for integrating processes with slow dynamics, a modified IMC design is proposed to deal with step or ramp type load disturbance as often encountered in practice. The controller parametrization is based on a two-degree-of-freedom (2DOF) control structure which allows for independent ...

the aim of this study was to determine the interactional effects of various video shows (skilled and self-model) and feedback type on performance and learning of dart throwing skill. 90 volunteers were randomly divided into 6 groups including self-control, experimenter control and yoked feedback that received either skilled model or self-model. three groups who watched the skilled model observe...
