Data on Control Engineering Reported by Researchers at University of London Imperial College

June 3, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Control Engineering are presented in a new report. According to news originating from London, United Kingdom, by VerticalNews correspondents, research stated, "Alternative and more efficient computational methods can extend the applicability of model predictive control (MPC) to systems with tight real-time requirements. This paper presents a system-on-a-chip MPC system, implemented on a field-programmable gate array (FPGA), consisting of a sparse structure-exploiting primal dual interior point (PDIP) quadratic program (QP) solver for MPC reference tracking and a fast gradient QP solver for steady-state target calculation."

Our news journalists obtained a quote from the research from the University of London Imperial College, "A parallel reduced precision iterative solver is used to accelerate the solution of the set of linear equations forming the computational bottleneck of the PDIP algorithm. A numerical study of the effect of reducing the number of iterations highlights the effectiveness of the approach. The system is demonstrated with an FPGA-in-the-loop testbench controlling a nonlinear simulation of a large airliner."

According to the news editors, the research concluded: "This paper considers many more manipulated inputs than any previous FPGA-based MPC implementation to date, yet the implementation comfortably fits into a midrange FPGA, and the controller compares well in terms of solution quality and latency to state-of-the-art QP solvers running on a standard PC."
