Discrete, Fractional Order, Cancellation Controller. Part II: PLC Implementation

摘要

In the paper the PLC implementation of discrete, fractional order cancellation controller dedicated to control a high order inertial plant is given. The controller uses the hybrid transfer function model of the plant. It is implemented at PLC SIEMENS with respect to object-oriented approach recommended by IEC61131 standard. Results of tests agree with simulations. The proposed controller is easy to tune and assures the better control performance than typical PID.
