Abstract
An aircraft environmental control system (4) for controlling a temperature of a fluid, the control system (4) comprising: a temperature sensor (30) configured to measure a temperature of the fluid and to generate a signal, the first signal being indicative of the measured temperature; a control signal generator (52) configured to, dependent upon the first signal, generate a control signal for controlling the temperature of the fluid; and one or more processors (64) configured to, responsive to determining that the measured temperature oscillates about a central value, decrease a gain of the control signal generator (52).

An aircraft environmental control system for controlling a temperature of a fluid, the control system comprising:
- a temperature sensor configured to measure a temperature of the fluid and to generate a first signal, the first signal being indicative of the measured temperature;
- a control signal generator configured to, dependent upon the first signal, generate a control signal for controlling the temperature of the fluid;
- and
- one or more processors configured to, responsive to determining that the measured temperature oscillates about a central value, decrease a gain of the control signal generator.
An aircraft environmental control method for controlling a temperature of a fluid, the control method comprising:
- measuring a temperature of the fluid;
- generating a first signal, the first signal being indicative of the measured temperature;
- generating, by a control signal generator, dependent upon the first signal, a control signal for controlling the temperature of the fluid;
- determining that the measured temperature oscillates about a central value;
- and, responsive to determining that the measured temperature oscillates about a central value, decreasing a gain of the control signal generator.
