DC Motor Speed Regulating Control System Based on the Model-free Adaptive Control Method

The model-free learning adaptive motion control system of DC motor based on data acquisition was designed.The model-free learning adaptive control(MFLAC) approach of a class of SISO nonlinear discrete-time systems based on linearization of entire format was applied to DC motor speed control.The design of controller is model-free.The control is very effective when model orders are too high that the classical adaptive control needs too much computering resource to deal with its heavy computation burden in order to meeting the requirement of the rapid system response.System consists of control components and real time simulation.Speed acquisition,motor control,parameter modification and track plotted of real time process are realized,programmed software is the Visual Basic,adopted of the dynamic-linked libraries(DLL) to control the data acquisition.Stability,validity and robustness against exogenous disturbance and noise are demonstrated by experimental results for the nonlinear systems of motor with vaguely known dynamics.
