For speech generation using small databases, spectral smoothing at the unit joints is necessary and can be realized by an interpolation of model parameters. For that purpose, the LSF are the best choice from the conventional parameter descriptions. This contribution shows how LSF interpolations can be improved using poles as parameters. The problem of the pole assignment between the two pole co...

The paper is concerned with defining and parametrising the families of all degenerate compensators (feedback, squaring down etc) in a variety of linear control problems. Such compensators indicate the boundaries of the control design, but they also provide the means for linearising the nonlinear nature of the Determinantal Assignment Problems, which provide the unifying description for all freq...

The idea of pole-region assignment is extended to interval gain and phase margin assignment. The internal model control proportional-integral-derivative IMC-PID design is examined from the frequency domain point of view. Equations for typical frequency domain specifications such as gain margin, phase margin and bandwidth are derived for the IMC-PID design. The gain and phase margins are monitor...

This paper focuses on using a singularly perturbed approach to derive a vibration damping control law in which a pole assignment feedback method is utilized. The composite control system is characterized by two components which can be computed separately. The one is Cartesian-based PI control which drives the end-effector of a flexible manipulator to track the desired time-based trajectory. The...

The design of decentralised control schemes has two major aspects. The selection of the decentralised structure and then the design of the decentralised controller that has a given structure and addresses certain design requirements. This paper deals with the parametrisation and selection of the decentralized structure such that problems such as the decentralised pole assignment may have soluti...

The paper aims at formulating an integrated approach for the selection of decentralized control structures using a number of structural criteria aiming at facilitating the design of decentralised control schemes. This requires the selection of decentralisation structure that will allow the generic solvability of a variety of decentralised control problems, such as pole assignment by decentralis...

INTRODUCTION Individual prediction of tumour behaviour based on molecular markers may refine adjuvant treatment strategies in endometrial cancer (EC). As these molecular alterations are determined in a small tumour fraction, high intratumour heterogeneity may interfere with correct risk prediction. This study aimed to investigate to which extent intratumour heterogeneity exists for molecular ma...
