Abstract:
In this paper, the concept of differential flatness is
applied to a controller with the aim of producing constant voltage
and frequency from a hydrokinetic with permanent synchronous
generator submitted to variable water flow. The idea of this
concept being to generate an imaginary trajectory that will take
the system from an initial condition to a desired output generating
power. The results show that, the generated output is dynamically
adjusted during the voltage regulation process. The advantage of
the proposed differential flatness based controller over the
traditional proportional integral (PI) control is that decoupling is
not necessary, as demonstrated by the modelling and simulation
studies under different operating conditions, such as changes in
water flow rate.
