Adaptive Control System for Weigh Feeder

摘要：

The present paper proposes a new method for designing a weigh feeder controller.A weigh feeder cannot be modeled accurately because its dynamic characteristics are time-varying and its high frequency vibration modes are not easily identied.In the present paper,a weigh feeder is approximated as a rst-order plus integrator system,and a self-tuning controller is designed on the basis of the approximated model to estimate its gain recursively.The purpose of this study is to design a controller to be actually employed in industry.To this end,a controller is assumed to consist of proportional gain for control error and steady-state control input.As a result,the proposed controller has a simple structure and its controller parameters can be understood intuitively.Consequently,the proposed design method can be easily adopted in industry.Numerical and experimental results demonstrate its effectiveness.
