WebThe block runs the motor using closed-loop field-oriented control (FOC) with a limited speed during which it runs the tests to estimate back-emf constant (K e) and viscous damping (B).After a pre-configured duration, the block concludes these tests to compute K e and B, and then, triggers coast-down by shutting down all six inverter switches. WebThe Detect Rise Positive block detects a rising edge by determining if the input is strictly positive, and its previous value was nonpositive. The output is true (equal to 1 ) when the input signal is greater than zero, and the previous value was less than or equal to zero. je suis zinzinWebMar 3, 2024 · The "Detect Increase" block is in the standard Simulink library, and converts our Boolean (which lasts the frequency of the event) to a single sample on the rising edge. You may not need this depending on what your E signal looks like, in my case it was required because E comes from a signal-builder pulse. lampekappen flamant
