FEEDBACK CONTROL METHOD AND UNIT OF A SERVO CONTROLLED SYSTEM WHICH AFFECTS THE PSYCHOPHYSICAL STATE OF A USER
First Claim
1. A feedback control method of a servo controlled system which acts on the environment surrounding a user for adjusting at least one feature of the environment which affects the psychophysical state of the user;
- the method comprising the steps of;
identifying at least one psychophysical feedback parameter of the user correlated with the perception that the user has of the environment feature adjusted by the servo controlled system;
determining a desired optimal value or a range of desired optimal values of the psychophysical feedback parameter;
cyclically estimating a real value of the psychophysical feedback parameter of the user by means of at least one measurement performed directly on the user; and
identifying at least one physical environmental feedback quantity related to the environment which surrounds the user;
determining a desired optimal value or a range of desired optimal values of the physical environmental feedback quantity;
cyclically measuring a value of the physical environmental feedback quantity by means of a measurement performed in the environment; and
cyclically driving the servo controlled system to seek both the desired optimal value of the psychophysical feedback parameter and the desired optimal value of the physical environmental feedback quantity using a first control loop, which is based on the physical environmental feedback quantity, and a second control loop, which is based on the psychophysical feedback parameter and corrects the action of the first control loop within a predetermined margin.
