Abstract
According to the invention, a Cartesian control means (16) comprising a phase rotator (50) and a phase adjuster (52) is provided. With a method and a device according to the invention, a system is provided that is unconditionally stable with respect to non-phase alignment, regardless of input power changes, temperature and component ageing. No certain conditions need to be placed upon the control system to ensure stability, i.e. the system is non-obtrusive and requires no off-line calibration. The inclusion of the phase rotator (50) and phase adjustment techniques into the Cartesian control system makes this possible.
