    Abstract: A field oriented control (FOC) system and method provides smooth field-oriented startup for three-phase sensorless permanent magnet synchronous motors (PMSMs) despite the absence of load information. The system uses the rotor flux projection on the d- or q-axis to determine whether the stator flux current reference being applied during reference startup phase is sufficient to spin the PMSM, thereby providing smooth operation during the reference startup phase and saving energy relative to applying rated current. The system also determines a suitable initial value for the stator torque current reference to use at the start of closed-loop sensorless FOC control mode based on an angle difference between the reference and estimated angles. Since this angle difference is reflective of the load on the PMSM, the selected initial value allows the system to achieve a smooth transition from reference startup mode to closed-loop sensorless FOC control mode.

    Abstract: An app store includes a plurality of state machines that describe the function of a product. The system allows a user to select at least one app from this plurality of apps. The user may also customize the state machine represented by the app or parameters thereof. The selected state machine can be translated into a format readable by a semiconductor device in a target platform without requiring the user to generate computer code. The app store can also transact rights to use the app represented by the state machine. The state machine may be executed in a simulation environment, on a reference platform or development board, or on a semiconductor device in an end-user product to facilitate control in accordance with the state machine defined by the state machine.
