The same hybrid nature of designing a digital filter for analog signals is also prevalent in digital signal processing. A crucial observation is that the perfect band-limiting hypothesis can be inadequate for many practical situations. In practice, the original analog signals (sounds, images, etc.) are neither fully band-limited nor even close to be bandlimited in the current processing standards. This is the problem of interpolating high-frequency components, which in turn is that of recovering the intersample behavior. Sampled-data control theory provides an optimal platform for such problems. This paper provides a new problem formulation, design procedure, and various applications in sound processing/compression and image processing.","PeriodicalId":169932,"journal":{"name":"2004 5th Asian Control Conference (IEEE Cat.

On the other hand, PID controllers have been widely used for process systems. Therefore, in this paper, a new design scheme of PID controllers based on a memory-based (MB) modeling is proposed for nonlinear systems. According to the MB modeling method, some local models are automatically generated based on input/output data pairs of the controlled object stored in the data-base. The proposed scheme generates PID parameters using stored input/output data in the data-base. This scheme can adjust the PID parameters in an on-line manner even if the system has nonlinear properties. Finally, the effectiveness of the newly proposed control scheme is numerically evaluated on some simulation examples.","PeriodicalId":169932,"journal":{"name":"2004 5th Asian Control Conference (IEEE Cat.

Simulation studies reveal the localisation and circling behaviour achieved with the various cost functions, and a new minimum estimation error configuration is discovered. A direct cost function based on an 'area-of-uncertainty' metric achieved the best localisation considering flight and localisation time.","PeriodicalId":169932,"journal":{"name":"2004 5th Asian Control Conference (IEEE Cat.

In order to compare different control structures, the performances of the closed loop controlled system are expressed by the poles' position. Attached to each input (output), the control effort (control contribution) is defined as the inverse of the maximum admissible delay in its path without provoking instability. This delay, that can be roughly estimated by the shift of the open-to-closed loop poles under the variable connection, is defined as the variable relevance in the control structure. As digital control implies open-loop control in the intersampling time interval, there is always a time delay in the updating of the control. Small time delays in the most relevant variables may result in unstable behaviour.","PeriodicalId":169932,"journal":{"name":"2004 5th Asian Control Conference (IEEE Cat.
