โœฆ Synopsis

The realization of an educational thyristor-driven magnetic levitation control system is described. The multiloop control includes the inner loop current dynamic control of the electrical subsystem and the outer loop ball position control of the mechanical subsystem. The proportionalintegral (PI) and proportional-derivative (PD) compensations are exploited to implement the controllers for the subsystems. Robustness analysis for the effect of current ripple guarantees and shows the capability of the thyristor D.C. driver in the magnetic suspension system. Real-time control of the experimental setup demonstrates the feasibility of this mechatronic design architecture.

In this study, we used a laser displacement sensor, which the resolution was precise over 2 lm and capable of measuring inยฎnitesimal displacement rapidly for magnetic levitation and suspension equipment. A feedback control was applied in this system, which required quick response to voltage variatio

Power system transient stability is one of the most challenging technical areas in electric power industry. Thyristorcontrolled series compensation (TCSC) is expected to improve transient stability and damp power oscillations. TCSC control in power system transients is a nonlinear control problem. T
