Controller and a method for controlling a process variable and a power supply circuit comprising a power supply and a controller
Abstract:
A controller (100; 200) for controlling a process variable (202) comprises an input interface (102) configured to receive a feedback signal indicative of an error between a process variable (202) to be controlled and a setpoint (104) for the process variable. At least a first integrator is (108) configured to derive an accumulated error signal using an integrator input signal depending on the feedback signal and at least one resonator having a predetermined resonance frequency is configured to provide a resonator output signal using a resonator input signal depending on the feedback signal. An output interface is (130) configured to provide a manipulation signal for influencing the process variable (202), the manipulation signal being derived using the accumulated error signal and the resonator output signal.
Abstract(Chinese):

用于控制过程变量（202）的控制器（100; 200）包括输入接口（102），其被配置为接收指示待控制的过程变量（202）和用于所述控制器（104）的设定点（104）之间的误差的反馈信号 过程变量。 至少第一积分器（108）被配置为根据反馈信号使用积分器输入信号导出累积误差信号，并且具有预定谐振频率的至少一个谐振器被配置为使用谐振器输入信号依赖于谐振器输入信号 对反馈信号。 输出接口（130）被配置为提供用于影响过程变量（202）的操作信号，所述操作信号是使用累积误差信号和谐振器输出信号导出的。
