| Abstract |
Actually variable speed drives with DC machines are operated using conventional speed and current
regulating loops. This control provides a good dynamic response and stationary behaviour, but it does
not say anything about the conversion efficiency. It is very well-known that in the transient
behaviour, as startings, stoppings or reversings, the efficiency of the energy conversion is diminished
down to the value smaller than 70 percent, while in the stationary state it is greater. The objective of
the paper is to develope a new control, of optimal type. This optimal control must minimize the
energy which will be consumed over the dynamic periods. The synthesis of the optimal control law is
accomplished with the experimental results, via the simulation procedure, and a proposal for the
implementation. |
