Method for controlling a discrete system

A system for controlling a controlled parameter that affects a target parameter of a target zone, the system comprising:

• a feedback control loop having a switching controller, a controlled device, and an averaging device;
• wherein the controlled device includes a time constant and a specified operational characteristic,
• wherein the controlled device includes a first operational state and a second operational state;
• wherein the averaging device includes a time constant based on the time constant for the controlled device, a controllable range of the controlled device, and the specified operational characteristic.

A system for controlling a controlled parameter that affects a target parameter of a target zone, the system comprising:

• a feedback control loop including:
• a switching controller;
• a controlled device having a time constant, a specified operational characteristic, a controllable range of the controlled device a first operational state, and a second operational state;
• and
• means for averaging a signal with a time constant based on the time constant for the controlled device, the controllable range of the controlled device, and the specified operational characteristic.

A method for controlling a device having discrete operating states that affect a parameter of a target zone having a first time constant, the method comprising:

• receiving a signal representative of a measured value of a controlled parameter of the device, the controlled parameter having a second time constant that is smaller than the first time constant;
• passing the measured value through an averaging device using a third time constant to provide an averaged value;
• producing a control signal representative of a deviation between the averaged value and a desired value of the controlled parameter;
• converting the control signal into a pulsed output signal that turns the device on and off.
