摘要： A switching power supply includes a circuit that provides an output voltage, a switching component that switches the circuit between a first output voltage state and a second output voltage state, and a driver component that receives an input control signal and that drives the switching component to cause the circuit to switch between the first output voltage state and the second output voltage state. An adaptive plant estimator receives the output voltage from the circuit and an input to the switching power supply and provides a model of the switching power supply that reflects changes in an output voltage state of the switching power supply. A compensator design component receives the model and provides compensator parameters that reflect changes in the output voltage state of the switching power supply. An adaptive compensator receives the compensator parameters and provides the input control signal to the driver component.

摘要： A controller for switching power supplies includes a nonlinear controller component capable of providing a duty cycle to a pulse width modulator. The duty cycle corresponds to at least one predetermining switching power supply state variable. A nonlinear controller component receives as inputs at least one predetermined switching power supply state variable. A relationship between duty cycle and at least one predetermined switching power supply state variable is obtained by a predetermined method. The nonlinear controller component comprises memory for access by an application component. The memory includes a data structure stored in memory and a plurality of duty cycles. Each of the plurality of duty cycles has a corresponding at least one predetermined switching power supply state variable. Each duty cycle, when provided to the pulse width modulator of the switching power supply, provides a predetermined switching power supply output.

A second multiplying component multiplies an input to the second multiplying component by a second model parameter. An adding component adds an output of the first multiplying component and an output of the second multiplying component. A delay component receives an output of the adding component and provides an output to an input of the second multiplying component.
