Higher order systems are based on second order systems. In case of mechanical second order systems, energy is stored in the form of inertia whereas in case of electrical systems, energy can be stored in a capacitor or inductor.

Consider the following block diagram of closed loop control system. Here, an open loop transfer function, $\frac{\omega ^2_n}{s(s+2\delta \omega_n)}$ is connected with a unity negative feedback. The applet below shows the response of a third order system with a cubic nonlinearity to a sine input.

parameters (,w, ) The applet shows that for w from to the frequency of the nonlinear response remains tied to the applied frequency while for the linear case the response is the sum of components at the natural frequency and applied frequency.

Adding a pole to a general second order system makes it a third order system and the dynamics can change dramatically. One example I can think of in which adding a pole or zero does not change the system dynamics dramatically is when the pole or zero is at much higher frequency than the pair of poles of the second order system.

y is the response of the measurement system component, x is the input to the measurement system component, n is the order of the system. Many measurement system components can be modeled by either first or second order differential equations.

series or parallel with either a voltage or current source we will form a RLC or second-order circuit. It is called a second-order circuit because of the second-order differential required to solve for the voltage or current.

The Korteweg-de Vries equation is a third order (partial) differential equation, describing waves on a shallow surface. I can't think of an example off the top of my head that isn't a PDE, but an example of a 4th order ODE would be the Euler-Bernoulli equation.

The Euler-Bernoulli equation describes how much a beam deflects under an applied load. The generalized procedure used in those methods consists of 3 steps Step 1: Calculate Base Shear = Factor f * Weight W where "f" is calculated from terms which take into consideration the Importance factor of the building, Site Class and soil characteristics, etc.

W is the total vertical weight derived from dead weight of the building and other imposed weights. We show that in the main case, system is transformed to a third-order system of nonhomogeneous linear first-order difference equations, which can be explicitly solved. This idea appeared for the first time in [ 24 ] for the case of the scalar equation with constant coefficients corresponding to system () and was also used later in [ 1, 4 ].Cited by: Frequency Response of Second-Order Systems.

It is important for the control system analyst to understand the complete relationship of the complex-frequency representation of a linear system, the poles and zeros of its transfer function, and its time-domain response to step and other inputs.
