This gives rise to an explicit compromise on the bandwidth of the external loop. In [13], [14], FCS-MPC is used for the inner current and torque control of the induction machine, maximizing its dynamic response, but a classical PI controller is still used for the outer speed loop.

Webb10 apr. 2024 · Under the Tuning tab, let’s set the controller requirements for the dq-axis current loops. For these loops we will set a target bandwidth of 3000 rad/sec with a phase margin of 80 degrees. The outer speed loop will run at least 10 times slower than the current loops so we will put in a bandwidth of 100rad/s. Webb13 mars 2024 · In this video, we show how to use reinforcement learning for field oriented control of a permanent magnet synchronous motor. To showcase this, we start with an example that uses the typical field oriented control architecture, where the outer loop controller is responsible for speed control; whereas the inner loop PI … WebbFigure 2: Simulation result of the PMSM with outer speed loop and inner current loop, under load torque step at 40ms Save the trace of the stator currents in the scope labelled “is_abc” under the name “Speed=700”.

The inner current loop turns the inductor into a voltage … WebbControl Arrangements for DC Drives. The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This has an inner feedback loop to control the current (and hence torque) and an outer loop to control speed.
