The Laplace transform is a well established mathematical technique for solving differential equations. It is named in honor of the great French mathematician, Pierre Simon De Laplace (1749-1827). Like all transforms, the Laplace transform changes one signal into another according to some fixed set of rules
The Laplace transform is deﬁned in terms of an integral over the interval [0,∞). In-tegrals over an inﬁnite interval are called improper integrals, a topic studied in Calculus II. DEFINITION Let f be a continuous function on [0,∞). The Laplace transform of f,
functions, the Laplace Transform method of solving initial value problems The method of Laplace transforms is a system that relies on algebra (rather than calculus-based methods) to solve linear differential equations.

Now, take the Laplace Transform (with zero initial conditions since we are finding a transfer function): We want to solve for the ratio of Y(s) to U(s), so we need so remove Q(s) from the output equation. We start by solving the state equation for Q(s) The matrix Φ(s) is called the state transition matrix. Now we put this into the output equation
