Abstract
A method and apparatus for signal transformation for positioning control in positioning systems is provided. The positioning involves performing a signal transformation by determining a transform and an inverse transform between a triangular reference signal and a model reference signal with less frequency content, for transforming the triangular reference signal into a ramp signal; and providing a controller including a double integral module, configured for tracking the model reference signal with zero steady state error, for controlling a positioning system.
Claims1
A method of signal transformation for positioning control in a positioning system, comprising:
- performing a signal transformation by determining a transform and an inverse transform between a triangular reference signal and a model reference signal with less frequency content, for transforming the triangular reference signal into a ramp signal;
- and
- providing a controller including a double integral module, configured for tracking the model reference signal with zero steady state error, for controlling a positioning system.
