An appliance includes a controller operably connected to a power circuit, a control circuit, a power source, a sensor for sensing a parameter level, and an active element. The controller is configured to receive an input of a parameter level from the sensor and output a duty cycle for controlling a power level of the active element via the control circuit at various times to achieve a target setpoint of the parameter, the duty cycle being based on proportional and integral control. The controller uses proportional control and integral control when the control circuitry is energized, and accumulates an integral error only when it is determined that the parametric process variable sensed by the sensor is within the interval of the target setpoint. 一种电器，包括控制器，其可操作地连接到功率电路、控制电路、电源、用于感测参数水平的传感器和有源元件。控制器被配置为从传感器接收参数水平的输入并且输出占空比，该占空比用于在各个时间经由控制电路控制有源元件的功率水平，以实现参数的目标设置点，占空比基于比例和积分控制。控制器在控制电路通电时使用比例控制和积分控制，并且仅在确定由传感器感测的参数过程变量在目标设置点的间隔内时累加积分误差。
