Luminary control system

A light source comprising:

• a light generator that generates a first light signal of a first wavelength at a first intensity that is set by a first control signal;
• a light monitor that generates a first monitor signal having an amplitude determined by said first intensity;
• a target signal generator that generates a first target signal having an amplitude indicative of a first target value;
• a difference circuit that generates a first error signal having a magnitude related to the difference of said amplitudes of said first monitor signal and said first target signal;
• a feedback controller that generates said first control signal in response to said first error signal;
• and
• an initial control signal generator that causes said feedback controller to generate a preliminary first control signal in place of said first control signal, said preliminary control signal being independent of said first error signal and being generated for a first time period after said first target value changes to a new first target value, wherein
• said light generator generates a second light signal of a second wavelength at a second intensity that is set by a second control signal,
• said light monitor generates a second monitor signal having an amplitude determined by said second intensity,
• said target signal generator generates a second target signal having an amplitude indicative of a second target value,
• said difference circuit generates a second error signal having a magnitude related to the difference of said amplitudes of said second monitor signal and said second target signal
• said feedback controller generates said second control signal in response to said second error signal;
• and
• said initial control signal generator causes said feedback controller to generate a preliminary second control signal in place of said second control signal, said preliminary control signal being independent of said first and second error signals and being generated for a second time period after either said first target value or said second target value changes, and
• wherein said light generator generates a third light signal of a third wavelength at a third intensity that is set by a third control signal,
• said light monitor generates a third monitor signal having an amplitude determined by said third intensity,
• said target signal generator generates a third target signal having an amplitude indicative of a third target value,
• said difference circuit generates a third error signal having a magnitude related to the difference of said amplitudes of said third monitor signal and said third target signal;
• said feedback controller generates said third control signal in response to said third error signal;
• and
• said initial control signal generator causes said feedback controller to generate a preliminary third control signal in place of said third control signal, said preliminary control signal being independent of said first and third error signals and being generated for a third time period after either said first target value or said third target value changes.
