Abstract
Modern industrial motion controllers are not commonly used in the control of laboratory equipment; therefore, a set of automation laboratory systems has been developed with the goal of integrating such a controller. A brief history of motion control, its aims, its size, and recent trends are presented initially. Then, examples are illustrated to provide a background of the types of control applications typically encountered in industry. As the AC motor is used ubiquitously in industry for the production of motion, a brief overview is presented of the servo and induction motor types with a discussion of their performance. To better understand the AC servo motor, a mathematical model of its electrical and mechanical operation was built using Simulink. The model incorporates parameters linked as closely as possible to the industrial motion controller being utilized. The motor and power stage simulations as well as the inner and outer control loops for velocity and torque control were also integrated into the model. A Park transformation was used to make constant an otherwise varying three-phase inductance that was necessary to create magnetic fields in an AC motor's stator. The model can be tuned, simulate a point-topoint move, and illustrate a disturbance rejection. Of the two laboratory systems developed, one is an automated warehouse capable of distinguishing four box types, load storage shelving, and move shelved product to a shipping zone where it is palletized. The other is a bottle filling station that can position empty bottle sets and fill them while the filling head remains just above the liquid level in the bottle. The software code necessary for the operation of each system was developed exclusively for each machine and is shown in abbreviated form as two sets of PLC and motion programs for each system, respectively. Each system was successfully run and the control models are now ready for future study.
