FPGA-Based Smart Induction Motor Controller Design

From a control viewpoint, DC motors must be maintained frequently due to their brushes and rectifiers. Sometimes the motor is installed in a location that makes it difficult or impossible to maintain or repair the motor. Compared to the disadvantages of DC motors, AC motors have a variety of advantages. for example, AC motors feature small size, light weight, low rotary inertia, and low price. Generally speaking, induction motors are nonlinear and time-varying with a dynamic coupling system, so the controller design is complicated. When considering control problems, various control theories are often proposed, e.g., proportion-integral-derivative control, sliding mode control, adaptive control, etc. These methods aim to make the system’s behavior comply with the design requirements for all system parameter variations and external interferences.
