Abstract
Controllers, method and programs for controlling machines are provided. For example, A method comprises determining a resistance value for a loss compensation resistor, updating at least one control equation based on an equivalent circuit using the resistance value and controlling the machine based on the updated at least one control equation. The resistance value represents a plurality of electro-magnetic losses of a machine. The resistance value can be determined from an inverse resistance value.
