Abstract
Linear control design was adopted for unstable controlled plant whose property was influenced by the unstable pole value Therefore designed results can not satisfy the requirement of disturbances rejection and robustness An effective nonlinear control design method which combined effectively with state feedback control and proportion integration–proportion differentiation PI–PD switching control was proposed in the paper Considered synthetically stability and dynamic property of controlled plant which combined with magnetic suspension controlled experiment in order to gradually improve the controller Finally PI–PD switching control based on state feedback control was taken as a nonlinear control design method which could make magnetic suspension controlled system stabilize suspension The method decreased steady state error eliminated stick slip phenomenon of control action with stable tracking and improved the robustness of the systemThis work was partly supported by the Youth Foundation of Hebei Educational committee No QN2015336 National Natural Science Foundation of China No 11404054 the Youth Foundation of Hebei Educational committee No ZD2016203 and Fundamental Research Foundation for Central Universities No XNB201608 No XNB201609
