Abstract (en)

A method to estimate a load behavior in a laundry treatment machine comprises the step of determining an inertia (Ĵ<sub>t</sub>, Ĵ<sub>L</sub>) and/or a load torque caused by a load depending on a first torque signal Tem*1, a second torque signal Tem*2, a derivative ω˙1^ of a first angular speed signal and a derivative ω˙2^ of a second angular speed signal. These signals are based on a first operation and a second operation of the laundry treatment machine, wherein a controller of the laundry treatment machine is operated with different controller parameters (P<sub>1</sub>, P<sub>2</sub>). The method enables to estimate the load behavior in an easy, reliable and accurate manner.
