In view of the controlled plant complexity of the horizontal position synchronization system in automatic filling machine, a novel approach of single neuron PID model reference adaptive control for AC permanent magnet synchronous motor (PMSM) servo control based on diagonal recurrent neural network (DRNN) on-line identification is proposed owing to the disadvantage of traditional PID controller. The...
4G cellular systems and the IMT Advanced candidates will provide broadband wireless access with QoS. Especially in multihop configurations of these systems the base station controls resources centrally while relays can take over a part of the responsibility on the second hop. To make this work on layer two, scheduling is the most important task. However, many dimensions of the problem lead to much...
Future cellular radio systems aim at maximizing the spectral efficiency. OFDMA radio resources are the scarce good with their dimensions bandwidth, time and space. Due to frequency selective fading the effective path-loss varies in all dimensions. Adaptive algorithms are available which allocate the best modulation and coding scheme depending on the expected SINR, as well as dynamic subchannel assignment...
