Webb17 maj 2024 · I specifically used Sys.sleep(0.5) for outer loop and Sys.sleep(1) for inner loop so that we can check what is happening : 2 cores are running in parallel [outer(0.5s) + not parallel [3 * inner(1s)]] ~ 3.5s. This calculation holds even if we increase the number of outer loops (up to the 6 cores available). – WebbThe inner control loop controls the motor current and motor torque below a safe limit. Consider a reference speed ω*m which produces a positive error Δ ω*m. The speed error is operated through a speed controller and applied to a current limiter which is overloaded even for a small speed error.

Webbintegral controllers (PI-FOC) consists of an outer speed loop and an inner current loop (see Figure 1). In order to achieve the desired motor speed, the outer loop provides a torque reference #ref to the inner loop, that runs at higher frequency and regulates the (d,q ) currents in order to track the torque reference. WebbThe inner loop needs a current controller and outer loop requires a voltage controller.
