This document provides instructions on how to implement Multi-rate control on Simulink with ACG SDK. It allows running part of the control at a slower rate, without impacting the real-time control running at the base rate. This is typically useful for implementing a finite state machine or running a tracking algorithm. Enable MultiTasking Make sure…
This technical note gives general insights on the implementation of coordinated control using imperix’s rapid control prototyping solutions. A grid-tied back-to-back three-phase inverter is given as an example, with the idea of showing how two B-Box RCP units would operate and communicate together when controlling such a converter. The provided Simulink files contain the plant…
The hall sensor interface (HAL) block provides access to the commutation signals from Hall effect sensors of a brushless DC motor. The B-Box RCP supports up to two machines with Hall sensors through the Motor Interface for B-Box RCP. Hall sensors are usually found in three-phase brushless DC machines and provide a 60° resolution on…
The GPO block sets the values of the General purpose outputs (GPO). Simulink block Signal specification The GPO pin is set if the input is >0. Parameters Device ID selects which B-Box/B-Board to address when used in a multi-device configuration. GPO bit selects one pin to control. Reset pin value to 0 in case of fault acts…
The Field-Oriented Control (FOC) method is a motor control strategy that orients the stator current vector in a rotating reference frame of the machine.
Some power sources, like solar panels, present power characteristics that strongly depend on the operating conditions. In such cases, Maximum Power Point Tracking (MPPT) is often applied to maximize the extracted power.
What is the space vector modulation technique (SVM) and how does it work? To answer these questions, this article introduces first the notions of active and zero space vectors and their representation in the Clarke referential. It presents then how to use space vectors to synthesize any output voltage with two or three-level inverters. A…
Imperix relies on the increasingly popular OPC UA industrial protocol to remotely control and monitor its power electronic controllers over Ethernet. To do so, the B-Board PRO and B-Box RCP controllers embed an OPC UA server to communicate with the in-house monitoring software imperix Cockpit. One of the advantages of using an open standard such…
