Example 1
Fig. 1 is a flowchart of a method for adjusting parameters of a controller based on a bode diagram, which is applicable to the case of adjusting parameters of a PI controller, and the application is widely applicable to control loop parameter adjustment of a micro inverter, a home energy storage inverter, a string inverter, and the like. As shown in fig. 1, the method includes:
s110, acquiring a circuit bode diagram and a controller bode diagram of the circuit control system, and determining a system amplitude-frequency curve of the circuit control system based on the circuit bode diagram and the controller bode diagram, wherein the bode diagram comprises an amplitude-frequency curve which is used for describing a curve of amplitude changing along with frequency.
Specifically, as shown in the schematic structural diagram of the control principle of the circuit control system shown in fig. 1b, the circuit control system is composed of a PI controller and a main control circuit, R(s) is an input signal, C(s) is a transfer function of the PI controller, G(s) is a transfer function of the main control circuit, and Y(s) is an output signal. Then a circuit bode diagram and a PI controller bode diagram of the circuit control system need to be acquired, where the PI controller bode diagram is well known in the art, and the method for acquiring the circuit bode diagram may be: determining a simulation model of the circuit, determining pulse data of the circuit based on the simulation model, wherein the pulse data at least comprises amplitude and frequency, determining a circuit bode diagram of a circuit control system based on the pulse data, and further superposing the circuit bode diagram and a controller bode diagram to determine a system amplitude-frequency curve of the circuit control system so as to facilitate the subsequent determination of a phase margin. In addition, the oscillograph or vector network analyzer is used for carrying out sweep frequency analysis on the physical circuit to obtain the circuit bode diagram.

After the current crossing frequency is obtained, the current crossing frequency and the system amplitude frequency curve are combined to obtain the current controller parameter under the current crossing frequency, and the phase frequency curve is also a function related to the controller parameter, so that the phase frequency curve of the circuit control system can be accurately determined by combining the current controller parameter, and the phase margin can be obtained according to the phase frequency curve and the current crossing frequency, so that the current phase margin of the circuit control system is determined based on the current crossing frequency and the system amplitude frequency curve, and the current phase margin is conveniently compared with the preset phase margin to adjust the controller parameter.
The first acquired current crossing frequency is the product of the switching frequency of the circuit control system and a preset value. For example, a factor of 10 of the switching frequency can be selected as the first acquired current crossover frequency, because of the higher immunity of such a system. The controller parameters may be a proportional coefficient Kp and an integral coefficient Ki.
S130, determining a target controller parameter according to a comparison result of the current phase margin and the preset phase margin.
The preset phase margin is set according to the actual test situation, and the preset phase margin is as large as possible to ensure the stability of the system, for example, may be set to 20.
Specifically, whether the current phase margin is larger than or equal to a preset phase margin is detected; if yes, the current controller parameter corresponding to the current crossing frequency is the target controller parameter; if not, the current crossing frequency is reduced according to the preset adjusting value, the adjusted current phase margin under the adjusted current crossing frequency is redetermined until the adjusted current phase margin is greater than or equal to the preset phase margin, and the adjusted current controller parameter corresponding to the adjusted current crossing frequency is the target controller parameter.
For example, as shown in fig. 1c, a simulation model of a circuit is determined, pulse data of the circuit is determined based on the simulation model, the pulse data at least includes amplitude and frequency, then a circuit bode diagram of a circuit control system is determined based on the pulse data, the circuit bode diagram and the controller bode diagram are further overlapped to determine a system amplitude-frequency curve of the circuit control system, for system stability, the current crossing frequency obtained for the first time is a product of a switching frequency of the circuit control system and a preset value, if 10 times of the switching frequency can be selected as the current crossing frequency obtained for the first time, then a current phase margin of the circuit control system is determined according to the current crossing frequency and the system amplitude-frequency curve, further judging whether the current phase margin is larger than or equal to a preset phase margin, if yes, then a current controller parameter corresponding to the current crossing frequency is a target controller parameter, if no, then the current crossing frequency is reduced according to the preset adjustment value, and the adjusted current phase margin is re-determined again, judging whether the current phase margin is larger than or equal to the preset phase margin, repeating the above processes until the current phase margin is larger than or equal to the preset phase margin, and then the current phase margin is determined to be the target controller parameter corresponding to the current controller parameter.
According to the technical scheme, a circuit bode diagram and a controller bode diagram of a circuit control system are obtained, a system amplitude-frequency curve of the circuit control system is determined based on the circuit bode diagram and the controller bode diagram, the bode diagram comprises an amplitude-frequency curve, and the amplitude-frequency curve is used for describing a curve of amplitude changing along with frequency; further acquiring the current crossing frequency of the circuit control system, and determining the current phase margin of the circuit control system based on the current crossing frequency and a system amplitude-frequency curve; and finally, determining the target controller parameters according to the comparison result of the current phase margin and the preset phase margin.
