The system comprises a drug delivery or dose regulator 103; a sensor 107 for measuring a biochemical or physiological property associated with the drug or the condition to be treated and generating a sensor signal. A controller 109 is configured to control the rate of delivery or dose of drug via the regulator in response to the difference in a measured biochemical or physiological property with respect to a target (an error). The controller (PID) comprises an active control component for generating an active output signal in response to the error signal; and a manipulation component which manipulates the active output signal to generate a post-manipulation signal for communication to the regulator as a final output signal. The controller further comprises an anti-wind up component for reducing or inhibiting the effect of signal wind up in the active control component and/or the manipulation component comprises a filter sub-component for conditioning the active output signal. The final output signal provides a controlled rate of delivery or dosage administered to a patient in response to the measured property. |
