Abstract
In described examples of methods and control systems to control a position and/or velocity of a machine, control circuitry is coupled to receive and dither a control signal, and to compute a control output value according to the dithered control signal and a control function. An inverter is coupled to the control circuitry, to control the position and/or velocity according to the control output value.
Claims23
A control system to control a position and/or velocity of a machine, the control system comprising:
- control circuitry coupled to receive and dither a control signal, and to compute a control output value according to the dithered control signal and a control function;
- and
- an inverter, coupled to the control circuitry, to control the position and/or velocity according to the control output value.
A circuit to control a position and/or velocity of a machine, the circuit comprising:
- an electronic memory;
- and
- a processor configured to execute program instructions stored in the electronic memory to:
- dither a control signal, and compute a control output value according to the dithered control signal and a control function.
A method of controlling a position and/or velocity of a machine, the method comprising:
- dithering a control signal;
- computing a control output value according to the dithered control signal and a control function;
- and
- controlling the position and/or velocity according to the control output value.
