Hey everyone! I'm working on an assignment, and I'm given a transfer function of a plant in the form of (random numbers): G(s) = 25 / s^3(10) + s^2(5) +s. I'm attaching a pole diagram. Does that look like a third-degree system which, after the dominant pole approximation, will behave like a first-order system? Open loop, btw.
Control system design methods that rely on linear plant models can’t directly work with time delays, but it is possible to extend a linear plant model to simulate the effects of a time delay. The resulting model is also linear and captures the approximate effects of the time delay.

Jan 01, 2011 · 1. Introduction Singular systems represent a more general framework for linear systems[1]. A singular model is an appropriate model for describing large scale interconnected systems, constrained robots and other differential algebraic systems with linear algebraic constraints[2].Also singular models can be utilized to model a system when the dependent variable is displacement and not the time[3].
Also, a general parametric eigenstructure assignment for MDSOL systems via proportional-derivative plus partial second-derivative state feedback is proposed. Based on this, the robust pole assignment problem is converted into an independent minimization problem.

Abstract/Summary. Numerical methods are described for determining robust, or well-conditioned, solutions to the problem of pole assignment by state feedback. The solutions obtained are such that the sensitivity of the assigned poles to perturbations in the system and gain matrices is minimized. It is shown that for these solutions, upper bounds on the norm of the feedback matrix and on the transient response are also minimized and a lower bound on the stability margin is maximized.
