Abstract: The invention relates to the field of (digitally controlled) electric motors, (digital) control system, (electric) motor based system including those (digital) control system and methods pertaining thereto. The invention addresses the complexity of dynamically switching between two or more different modulation algorithms such as SVPWM (Space Vector Pulse Width Modulation), SPWM (Sinusoidal Pulse Width Modulation), THIPWM (Third Harmonic Pulse Width Modulation), DPWM (Discontinuous Pulse Width Modulation), OPP (Optimized Pulse Pattern).

Abstract: A system, and in particular a system operating in real-time, may have its operation rely on a particular sequence of trigger signals, hardware or software, for proper operation. A trigger sequence checker provides a way to monitor in real-time predetermined sequences of triggers and is configured to generate an error signal upon detection of a faulty operation or sequence. Rules for sequences of triggers are stored in memory and are used by the trigger sequence checker to verify one or more sequences of triggers received as an input to the checker. A plurality of triggers may be handled by the checker. In one embodiment the checker is configurable to be set in a learning mode to capture triggers rules.
