steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability criterion provides a means for determining stability without evaluating the roots of this equation. The steady-state characteristics are obtainable from the open-loop transfer function for unity feedback systems (or equivalent unity-feedback systems)‚ yielding figures of merit and a ready

Math 251: The Annihilator Method: Using higher order homogeneous equations to solve non-homogeneous equations The annihilator method is a fast method for solving certain non-homogeneous differential equations. A variation of this method is sometimes called the “method of judicious guessing” or the “method of undetermined coefficients.” In each variation‚ the work that must be done is the same; the difference is only in the background understanding of why the work is being done. The key idea of the

yx‚ y ’ ’x‚…‚ynx=f(x) As in the case of second-order ODEs‚ such an ODE can be classified as linear or nonlinear. The general form of a linear ODE of order is an(x)dnydxn+an-1(x)dn-1ydxn-1+…+a1(x)dydx+a0xy=f(x) If f(x)is the zero function‚ the equation is said to behomogeneous. Many methods for solving higher order ODEs can be generalized to linear ODEs of ordern‚ where nis greater than 2. If the order of the ODE is not important‚ it is simply called a linear ODE. a).

MA1506 LECTURE NOTES CHAPTER 1 DIFFERENTIAL EQUATIONS 1.1 Introduction A differential equation is an equation that contains one or more derivatives of a differentiable function. [In this chapter we deal only with ordinary DEs‚ NOT partial DEs.] The order of a d.e. is the order of the equation’s highest order derivative; and a d.e. is linear if it can be put in the form any (n)(x)+an−1y (n−1)(x)+· · ·+a1y (1)(x)+a0y(x) = F‚ 1 where ai‚ 0 ≤ i ≤ n‚ and F are all functions of x.

Partial Fractions A way of "breaking apart" fractions with polynomials in them. What are Partial Fractions? We can do this directly: Like this (read Using Rational Expressions to learn more): 2 + 3 = 2·(x+1) + (x-2)·3 x-2 x+1 (x-2)(x+1) Which can then be simplified to: = 2x+2 + 3x-6 = 5x-4 x2+x-2x-2 x2-x-2 ... but how do we go in the opposite direction? That is what we discover here: How to find the "parts" that make the single fraction (the "partial fractions")
