/*! \brief Root class for controllers of PMSM
 * 
 * It defines the interface for controllers that connect to the pmsmDSctrl. 
 * The adapt() function calls bayes() of an internal BM. Note that it is assumed that the estimator is compatible with PMSM system.
 * I.e. it must have rv={ia, ib} and rvc={ua,ub}, any other BM will not work.
