Laboratory Sessions: Module 2

Part of the Power Systems book series (POWSYS)


A series of laboratory modules will be discussed in this chapter, which have been designed to lead the reader through the development phases needed to understand and work with a sensorless field-oriented PM drive. Sensorless control implementation is based on the use of the InstaSPIN algorithm, which will be used in different modes of operation. This implies use of the algorithm as a ‘software encoder’ as well as full motor identification, online resistance estimation and field-weakening. Implementation phases B, C and C+ are discussed in this chapter. For phase B development a so called ‘processor in the loop’ (PIL) approach is introduced in which case the processor is part of the simulation process. This approach is required because the sensorless algorithm resides in hardware only.
