Abstract
A method for determining an operating force (F) of a positioning actuator (), whose adjustment movements are produced by virtue of an appropriate supply of a working medium via actuating at least one valve (to) associated with the positioning actuator (). The operating force (F) is determined by computational determination. To be able to carry out the computational determination of the operating force (F) with little effort, by the at least one valve (to) in each case, a respective, essentially constant mass flow ({dot over (m)}, {dot over (m)}) of working medium is maintained either into the positioning actuator () and/or out of the positioning actuator ().
