Abstract EAST Articulated Maintenance Arm (EAMA) is a 8-DOF redundant articulated serial manipulator utilized to conduct maintenance tasks in EAST (Experimental Advanced Superconducting Tokamak). Due to the redundancy and total length (8.7395 m) of manipulator and the narrow space in the CASK and the curved vacuum vessel(VV), it is difficult to ...

The aim of this work is to extend the proposed NMPC approach for multi-step predictive control of nonlinear SISO processes. The calculation method will be derived for multi-step predictive control of a nonlinear SISO process. Then the proposed approach will be examined by applying it to two well-known control problems (a first-order, irreversible ...

Nonlinear Model Predictive control (NMPC) of fixed pitch variable speed wind turbine
2008 IEEE International Conference on Sustainable Energy Technologies, 2008Wind power has become one of the most attractive energy systems in several decades due to its rich wind power available and high turn back value than other types of renewable energy systems. The classical wind turbines are normally fixed pitch constant speed which have less power efficient and high dynamics loads that results in reducing life cycle of ...

Nonlinear Model Predictive Control (NMPC) for Free-Floating Space Manipulator
2018Manipulators are widely used in orbital operations, for example, Mobile Servicing System on the International Space Station and Shuttle Remote Manipulator System are used for several years. Such manipulators are operated by astronauts and mounted on large platforms, thus influence of manipulator motion on the state of the platform is not significant ...

Advanced process control of pantolactone synthesis using nonlinear model predictive control (NMPC)
2005Abstract In this paper, the discontinuous synthesis of racemic pantolactone has been described. The chemical steps of the synthesis take place in two stirred tank reactors, operated batchwise. The chemical reactions are highly exothermic. For a good quality of the product, the reactor temperature must be maintained between 12–14°C.

The combined system formed by a dual-arm space manipulator and a captured space target exhibits complex characteristics such as high nonlinearity, high redundancy, and strong closed-chain constraints. The dual arms drive the space target through contact forces, which simultaneously disturb the base.
