In this paper we discuss the linear quadratic (LQ) optimization problem subject to fractional order irregular singular systems. The aim of this paper is to find the control-state pairs satisfying the dynamic constraint of the form a fractional order irregular singular systems such that the LQ objective functional is minimized. The method of solving is to convert such LQ optimization into the standard...
Driver-in-the-loop and different human-machine goal consistency should be considered when designing driver-AFS interactive steering control system. In this paper, a novel design approach, namely dynamic game theory is used for the modelling of shared steering control between driver and AFS. Linear Quadratic dynamic optimization approach is used to derive the non-cooperative Nash, non-cooperative Stackelberg,...
Badly-scaled matrices or matrix pencils can reduce the reliability and accuracy of computed results for various numerical problems, including the computation of spectra and bases of invariant or deflating subspaces, which are used in many basic procedures for optimal and robust control, model reduction, spectral factorization, and other domains. Standard balancing techniques can often improve the...
Solving standard continuous-time algebraic Riccati equations using the structure-exploiting Hamiltonian approach is briefly presented. A new solver based on the SLICOT Library subroutines has been developed and tested on the CAREX benchmark collection included in SLICOT. The numerical results show similar or better accuracy (in terms of the relative residuals, or relative errors, when exact solutions...
This paper addresses the issues associated with the modeling and control of a novel dasiapseudopsila direct-drive machine which is realised by mechanically and magnetically combining a magnetic gear and a permanent magnet brushless electrical machine for general applications that require torque or speed control. It has been shown that due to lack of damping in the system, torsional oscillation may...
