Multirate filtering technique is widely used for meeting the sampling rates of different subsystems connected in cascade. Realization of Multirate system is cheaper than single rate system. But still it has huge scope to optimize the Multirate filters. This paper reviews different approaches for optimizing Multirate digital filter based on various optimization techniques such as Pipelining, Par...

In this paper, our recent studies on multirate sampling control and its application to motion control systems are reviewed. Especially, multirate two-degreeof-freedom controllers are focused on, where it is restricted that the sampling period of plant output is longer than the control period. The proposed controllers assure perfect tracking control (PTC) and perfect disturbance rejection (PDR) ...

This paper proposes a multirate control algorithm to guarantee the stability of haptic dental training system. In terms of a high-frequency force interpolating model, a multirate system with two levels up-sampling is introduced. The first level up-sampling achieves the haptic rendering with 1K Hz and the second level achieves the interpolating algorithm with 10K Hz or higher. Due to the slow ve...

The multirate filtering techniques are widely used in sampling rate conversion systems, and for constructing filters with equal input and output rates. Various multirate design techniques provide that the overall filtering characteristic is shared between several simplified sub-filters that operate at the lowest possible sampling rates. Design constraints for sub-filters are relaxed if compared...

The use of sampled-data multirate-output controllers for model reference adaptive control of possibly nonstably invertible linear systems with unknown parameters is investigated. Multirate-output controllers contain a multirate sampling mechanism with different sampling period at each system output. Such a control allows us to assign an arbitrary discrete-time transfer function matrix for the s...
