Abstract:
This paper presents details regarding the design of two state feedback control (SFC) solutions for the position control of a mechatronics application represented by the Model 220 Industrial Plant Emulator. Since SFC is not effective in terms of zero steady-state control error, the SFC structure of both solutions is inserted in a control loop that contains a PID controller with or without low-pass filter. This leads to the two SFC solutions proposed in this paper and dedicated to mechatronics applications with variable moment of inertia. The PID controllers are tuned by the Modulus Optimum method to ensure high control system performance expressed as increased phase margins and improved tracking performance. The performance of the proposed SFC solutions is illustrated by case studies that deal with experimentally identified parameters in two situations, rigid body dynamics and flexible drive dynamics. Simulation and experimental results obtained for the three significant values of the
moment of inertia of the load disk are given.
