Survey and Conclusion
The material presented in the last seven chapters contributes to the experimental realization and to the critical judgement of new adaptive control concepts recently proposed. The plant to be controlled consists of a separately excited DC-motor fed by a single-phase fully-controlled dual-converter. Variations of the moment of inertia, field excitation and load torque are possible. Moreover, the single-phase supply causes the discontinuous current domain to be wide. It is known that when the current is continuous, the motor armature can be regarded as a first order system, but when the current is discontinuous, it changes into a nearly nonlineargain system. All these variations make the application of adaptive solutions for the motor speed control attractive. On the other hand, the fast electro-mechanical system and the complex adaptive algorithm challenge the use of new developments of microelectronics.
