For some disturbances and model uncertainties of the multi-tank level system, we develop an adaptive nonlinear control law based on the neural network to achieve high performance control. A nonlinear model including the model uncertainties and disturbances is firstly built through carefully analyzing the multi-tank level system. Based on the model, the level controller is designed, in which the...

Abstract: The object of this study is to develop a self-tuning fractional order proportionalintegral-derivative (SFOPID) controller for controlling the mover position of a direct drive linear voice coil motor (VCM) accurately under different operational conditions. The fractional order proportional-integral-derivative (FOPID) controller can improve the control performances of the conventional i...

In order to solve the strong coupling characteristic of the temperature and humidity in wireless greenhouse environmental simulation test system which is with nonlinear, big lag, strong coupling, time-varying characteristics and so on, this study proposed an adaptive prediction decoupling method based on dynamic matrix control algorithm. This method can effectively overcome the influence of con...
