The Short Sampling Period in Adaptive Control

Popis výsledku v původním jazyce

The use of short sampling period in adaptive control has not been described properly when controlling the real process by adaptive controller. On one hand faster disturbance rejection due to short sampling period can be an advantage but on the other handit brings us some practical problems. The new approach to analysis of on-line identification methods based on one-step-ahead prediction clears up their sensitivity to disturbances in control loop and explain why should be neural network based identification better then classical by using of short sampling period. Particularly, quantization error and finite numerical precision of industrial controller must be considered in the real process control. The quantization effect is more known for example in instrumentation theory or signal processing theory than in control theory. Furthermore, in control theory the phenomenon has been usually disregarded. It is due to the fact that the conditions used in process control allow the quantization
