Abstract :
This paper deals with the study of a constant-power inverter and its controllability analysis. This
process is used in train air-conditioning power supply. Because of the load at constant power, in the
absence of specific control law, this system is characterized by an unstable behaviour. This problem
can be solved by adding a passive device, however this solution leads to losses of power. An
alternative and more interesting solution is to introduce an active solution by means of closed loop
regulation, however some internal variables of this system have a small degree of commandability,
which makes difficult the achievement of this solution. First, the system is studied: modelling, stability
and controllability analysis, study of passive stabilisation. Then the active control law developed is
presented. More precisely, a methodology is described for the design of a control law, which permits
on one hand to stabilize the inverter without adding any complementary passive device, and on the
other hand to let the output voltage track a sinusoidal reference signal. Finally, some numerical results
are given to show the efficiency of such a law.

Keywords : Inverter, pole placement, LQ control law, controllability, inverter controllability.
