Several alternative learning control algorithms are discussed, both from an inverse dynamics and an optimization point of view. The learning laws are derived in discrete time and do not need acceleration measurements. A simple algorithm using a const

The reference trajectory is normally known in advance in manipulator control which makes it possible to apply linear quadratic optimal tracking. This gives a control system which rounds corners and generates optimal feedforward. The method may be use

Several methods for task space control of kinematically redundant manipulators have been proposed in the literature. Most of these methods are based on a kinematic analysis of the manipulator. In this paper we propose a control algorithm in which we

A framework for the learning control of robots based on a parameterized control space is doscussed. Emphasis is put on how to utilize stored motion knowledge. The principles are applied to an example of redundancy resolution for a simple manipulator.

This article is concerned with the impact of voltage or power dips on large electric driven gas compressors (EDC) in typical oil and gas applications. EDCs are sensitive to voltage dips affecting the operation of the gas compression process through t

Grid voltage disturbances pose serious problems to gas compression stations powered by drives such as load commutated inverters (LCI). Until recently, drive control systems used in industrial practice were not capable of handling reduced grid voltage

Performance-based maintenance of machinery relies on detection and prediction of performance degradation. Degradation indicators calculated from process measurements need to be approximated with degradation models that smooth the variations in the me

Norwegian gas export is a high value business, where small and transient disturbances may cause substantial production losses. Process experience has shown that the compressor system may suffer considerably owing to surge and rotating stall in situat

Knowledge of compressor system behaviour during a trip is essential to obtain reliable operation. Experience at a gas treatment plant has shown that the export compressors (43 MW) may enter the unstable area of the performance characteristics and suf
