Overall strategy for fabric folding machine system control

摘要

Control of the machine carriage at a steady speed is crucial when one wants to advance the state-of-the-art with higher productivity and efficiency for fabric folding machine systems. Three steps are necessary. First, a good design-based model of the plant needs to be developed. Second, a good, realizable actuator, sensor, and controller must exist. Third, the system output should be modified using knowledge of the system’s dynamic response. This project presents a complete control strategy for a fabric folding machine system. In Part I, we illustrate the system’s mathematical modeling, dynamic analysis, linearization, and controller design. A very realizable actuator and sensor, which uses a motor and an encoder, are applied to design the control system. The computer simulation results for linear and nonlinear system models indicate that the system’s steady-state errors for this designed controller can be eliminated and that a good tracking property can be achieved as well.
