High control bandwidth is usually restricted in a photoelectric tracking system (PTS) based on Charge-Couple Device(CCD) with time delay, which hinders good performance. Generally, model-based delay-compensation controller called Smith predictor (SP) can help increase the gain to promote by separating delay from loop. However, performance promotion insufficient because still stays forward chann...

in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic f...

To describe stress and coping in families of children with Smith-Magenis syndrome, the present authors interviewed and received questionnaires from families of 36 children with this disorder. For measures of total stress, and of parent and family problems, the best predictors were the family's number of friends and the child's degree of impairment on the Vineland socialization domain; the singl...

A compliant constant-force actuator based on the cylinder is an important tool for contact operation of robots. Due to nonlinearity and time delay pneumatic system, traditional proportional–integral–derivative (PID) method constant force control does not work so well. In this paper, improved PID combining a backpropagation (BP) neural network Smith predictor proposed. Through MATLAB simulation ...

In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
