Lumped parameter modelling of ferroelectric ceramics for control applications using simulink
Abstract
Simplifying the constitutive behaviour of a material in terms of the lumped parameter elements is useful to design plant models in control engineering. In this contribution, a lumped parameter modelling approach is used to represent the constitutive behaviour of ferroelectric ceramics. Using the elements available in simulink, an electrical circuit is designed to simulate the ferroelectric behaviour. The simulation results of dielectric and butterfly hysteresis shows the possibility of applying the lumped parameter modelling approach in the design of displacement control systems.
