Experiments were conducted to illustrate the performance of a flywheel energy storage system (FESS) for electrical engineering technology students. The flywheel was coupled to a permanent magnet synchronous machine (PMSM), which can motor to accelerate the flywheel, and which can regenerate electrical power by extracting energy from the flywheel. The PMSM was connected to a battery bank and DC motors...
The paper describes how a Direct Torque Control (DTC) drive technology has been applied to provide improved torque control of a Flying Dividing Shear (FDS) system in a steel rolling mill. The control system has a supervisory level ensured by a Programmable Logic Controller (PLC). The FDS is a highly dynamic, high speed application load and requires a high performance torque control drive for the purpose...
