The present disclosure describes a load/unload control method for a compressor system with a rotating compressor connected to a pressure vessel. In the method, the present operating state can be monitored on the basis of a monitored/estimated electrical quantity of the compressor system. The method comprises an identification phase and an operational phase. In the identification phase, the compressor is operated at a constant rotational speed to generate two known pressures to the pressure vessel. At least one electrical quantity is monitored, and values of the electrical quantity corresponding to the pressure limits are stored. In the operational phase, reaching of a pressure limit may then be detected by comparing the present value of the monitored electrical quantity to the stored values.

An annular cylinder chamber (C1, C2) of a cylinder (21) is partitioned into an outer cylinder chamber (C1) and an inner cylinder chamber (C2) with an annular piston (22). The cylinder (21) is caused to eccentrically rotate by driving an electric motor (30), thereby changing the volumes of the outer cylinder chamber (C1) and the inner cylinder chamber (C2). The volume ratio Vr of the inner cylinder chamber (C2) to the outer cylinder chamber (C1) is set at about 0.7. In this state, the output torque of the electric motor (30) is changed in accordance with a variation in the load torque in one turn of rotation.
