Abstract
In a generator feeding a load that requires a current of special waveform, for example a nuclear fusion reactor laboratory equipment, the field excitation of the generator is controlled to meet the requirement of the load by means of a computer which generates a control signal to provide an optimum excitation to the generator for meeting the requirement of the load.
Claims3
A control system for a generator comprising:
- a generator having a field winding,
- a digital computer, said digital computer including memory means for storing a predetermined optimum pattern of the field excitation of said generator,
- a digital analogue converter for converting the digital signal produced by said digital computer into an analogue signal for controlling the excitation of said field winding,
- a load energized by said generator, said load comprising a plasma device including a field coil requiring an excitation current having a rectangular waveform, and
- means responsive to said optimum pattern for causing said computer to generate an optimum control signal required by the characteristics of said load, thereby controlling the field excitation of said generator in accordance with said optimum control signal.
