Abstract
A method for operating an electrical drive system includes the steps of: acquiring a number of input variables pertaining to the electrical drive system; determining at least one state variable from the acquired input variables by way of an observer; determining at least one disturbance variable from the acquired input variables by way of the observer; controlling the electrical drive system on the basis of the at least one determined state variable; and monitoring the state of the electrical drive system by machine learning, the at least one disturbance variable forming input data for a machine learning model.
Claims7
A method for operating an electrical drive system, the method comprising the steps of:
- acquiring a number of input variables (e1, . . . , en) pertaining to the electrical drive system;
- determining at least one state variable (Z) from the acquired input variables (e1, . . . , en) via an observer;
- determining at least one disturbance variable (S) from the acquired input variables (e1, . . . , en) via the observer;
- controlling the electrical drive system based on the at least one determined state variable (Z);
- and
- monitoring a state of the electrical drive system via machine learning, the at least one disturbance variable (S) forming input data for a machine learning model,
- wherein the electrical drive system comprises an electric motor, a phase-rotation indicator mechanically coupled to the electric motor, a mechanical load moved by the electric motor, and a load sensor mechanically coupled to the mechanical load.
