Abstract

A circuit breaking apparatus (100) comprises a circuit breaker (110), a motor drive system (120), and a controller (150). The circuit breaker (110) is electrically connectable to a power line (115). The motor drive system (120) is mechanically coupled to the circuit breaker (110) and configured to operate the circuit breaker (110) such as to perform a movement including at least an opening movement from a closed position to an open position, thereby electrically interrupting the power line (115). The controller (150) includes a model (155) of at least one of the motor drive system (120) and the circuit breaker (110).The controller (150) is configured to receive reference travel curve information (200) of the movement; generate actuator information (210) from the reference travel curve information (200) based on the model (155); and output the actuator information (210) to the motor drive system (120) to control a travel curve via model-based control.
