Solving a System Equation

Posted by Jeff on Dec 30, 2009 in Differential Equations, Linear Systems

Often during a course you will need to be able to solve a system equation for its roots.  These roots can be complex, distinct, or repeated.  These problems usually arise when working with linear systems or differential equations.  A system equation is formatted as follows:
System Equation:
For example purposes, I will solve a system equation [...]

Zero Input Response

Posted by Jeff on Sep 25, 2009 in Zero-Input Response

The total response of a given system can be expressed as the sum of two components: the zero-input component and the zero-state component:
Total response = zero-input response + zero-state response.
Our system:
Where represents our input and represents our output.
The zero-input response, which we will be solving for here, is the system response when [...]

Laplace Transforms

The Laplace Transform is a method that simplifies integral and differential equations into algebraic equations. This practice is commonly used to solve for a function out of a differential equation, which otherwise may have been unsolvable or very difficult. The following integrals can be used to transform between where denotes Laplace and [...]
