This paper discusses a design method for a sample-date system, in which a continuous-time plant is controlled using a discrete-time controller. It is assumed that the sampling interval of plant output is an integer multiple of the hold interval of control input, that is, the control system is a multirate system. Using the state-space representation, a multirate control law, which stabilizes a closed-loop...
This paper proposes a new control method for a weigh feeder. A weigh feeder has been widely employed in industry because it can dispense powder at a specified rate or amount. The proposed controller is mainly divided into a feed-forward and a feedback compensators. In order to obtain a simple controller, the former gives a steady-state control input designed using a nominal plant gain, and the latter...
