Higher order system model - PCI

We have considered a single tank and developed the literalized model of it. So it has a single time constant t. But there are more complex processes.

Let us take the case of a second order system. A system with second order dynamics can be classified as follows:

Second order systems : Two first order systems in series non-interacting

When a material or energy flows through a single capacity, we get a first-order system. If on the other hand, mass or energy flows through a series of capacities, the behaviour of the system is described by second-order dynamics. In the Fig. 3 tank1 feeds tank2, and hence affects its dynamic behaviour, whereas the opposite is not true. Such a system is characteristic of ‘non-interacting’ first order systems in series.
