Robust optimal control of linear discrete-time systems using primal-dual interior-point methods
Robust control application model linear discrete
2015/8/11
This paper describes how to efficiently solve a robust optimal control problem using recently developed primal-dual interior-point methods. Among potential applications are model predictive control. T...
In complex problems it may, however, be very expensive or infeasible to determine the Hessian matrix A.
This motivates quasi-Newton methods which recursively estimate A of A−1
from the measure...
Asynchronous Hybrid Systems with Jumps -- Analysis and Synthesis Methods
Synthesis Methods Analysis
2015/6/19
In this paper we show that the H-infinity synthesis problem for a class of linear systems with asynchronous jumps can be reduced to a purely discrete time synthesis problem. The system class considere...
