a spring. When there are two different types of energy-storage elements, the transient responses can be much more interesting than the simple exponential curves that
Typical examples are the spring-mass-damper system and the electronic RLC circuit. Second-order systems with potential oscillatory responses require two different and independent types of energy storage, such as the inductor and the capacitor in RLC filters, or a spring and an inert mass.
A second-order circuit is characterized by a second-order differential equation. It consists of resistors and the equivalent of two energy storage elements Finding Initial and Final Values First, focus on the variables that cannot change abruptly; capacitor voltage and inductor current.
stem and the system orderSecond order systems, like first order systems, are an extremely important class of systems. In previous chapters, we saw that the natura response of first order systems decays exponentially with time – the natural response decays monotonically to zero. The natural response of second order systems ca
Thus the second-order system in this limit of zero mass properly devolves to the first order case studied in Section 1.1.1. Figure 1.33: Initial condition response for second-order system in the over-damped case, with n = 1 and = 1, 2, 5, 10.
If > 1, then such a second-order system is overdamped, and the poles are at distinct locations on the negative real axis. This case can also be thought of as two independent first-order systems. The electrical circuit shown below can be described by a 2nd order homoge neous die rential equation.
A mechanical second-order system will have a spring element and an inertia element, an electrical system capacitance and inductance. An example of a control system which behaves as a second-order system is the idling control system used with a car engine. The important issue is how the engine runs when there is a sudden change in engine load.
