An adaptive control system incorporating self-teaching and self-programming features senses a pair of input signals for providing an output control signal. In a medical situation, the output signal drives a medicine delivery system in response to the sensing of a precursor signal and a condition signal which represent the future and the present states of a patient's health. Memory is provided in the form of a set of integrators which accumulate quantities of data representing the joint occurrence, during a measurement interval, of the precursor and the condition signals as quantized into preset ranges of values. Generation of the output signal is based on the amount of stored data as well as on the presence of a condition signal indicating a hazardous condition. Circuitry is provided for the selective incrementing and decrementing of the contents of the integrators in a manner analogous to the encouragement and punishment in a learning process.
