A method for controlling an electrical actuator for a wastegate valve arrangement of an exhaust gas turbocharger in an internal combustion engine is provided. A wastegate is situated in a bypass channel of the exhaust gas turbocharger. The method includes closing or opening the wastegate by the actuator for adjusting the exhaust gas flow routed past the exhaust gas turbocharger via the bypass channel. The wastegate is exposed to a predetermined closing force while it is in a closed state so as to regulate the closing force to a desired value for the closing force as a function of an actual value for the closing force. Computer-readable mediums embodying a computer program product having a program to perform the method are also provided.
