Abstract

The invention relates to a parameter setting method for a robust controller of a direct current motor, and belongs to the technical field of automatic fractional order control. The parameter setting method is applied to the direct current motor in a position servo system. The transfer function is that , the transfer function of the FO[PI] controller to be subjected to setting is that , the Bode diagram of the controlled object P(s) is drawn up through a MATLAB, the module value m and the phase angle n at the frequency are obtained; through C(s)P(s)=G(s), the equation about integral order lambda is solved through the MATLAB, through the stability condition, the proportionality coefficient and the differential coefficient are solved, through the obtained lambda, the obtained Kp and Ki are substituted into the formula that . The parameter setting method has the advantages that the calculation amount of the parameter setting of the controller is reduced, and the parameter setting process of the factional order FO[PI] robust controller is simplified.
