  • Constrained LQR for Low-Precision Data Representation 
    Longo, Stefano; Kerrigan, Eric C.; Constantinides, George A. (Elsevier Science B.V., Amsterdam., 2014-01-24)
    Performing computations with a low-bit number representation results in a faster implementation that uses less silicon, and hence allows an algorithm to be implemented in smaller and cheaper processors without loss of ...
  • Energy-aware MPC co-design for DC-DC converters 
    Suardi, Andrea; Longo, Stefano; Kerrigan, Eric C.; Constantinides, George A. (Institute of Electrical and Electronics Engineers, 2013-07-22)
    In this paper, we propose an integrated controller design methodology for the implementation of an energy-aware explicit model predictive control (MPC) algorithms, illustrat- ing the method on a DC-DC converter model. The ...
  • Number representation in predictive control 
    Kerrigan, Eric C.; Jerez, Juan L.; Longo, Stefano; Constantinides, George A. (Elsevier, 2012-09-30)
    In predictive control a nonlinear optimization problem has to be solved at each sample instant. Solving this optimization problem in a computationally efficient and numerically reliable fashion on an embedded system is a ...
  • A predictive control solver for low-precision data representation 
    Longo, Stefano; Kerrigan, Eric C.; Constantinides, George A. (Institute of Electrical and Electronics Engineers, 2013-07-22)
    We propose a method to efficiently exploit the non- standard number representation of some embedded computer architectures for the solution of constrained LQR problems. The resulting quadratic programming problem is ...
  • Robust explicit MPC design under finite precision arithmetic 
    Suardi, Andrea; Longo, Stefano; Kerrigan, Eric C.; Constantinides, George A. (Elsevier, 2014-08-29)
    We propose a design methodology for explicit Model Predictive Control (MPC) that guarantees hard constraint satisfaction in the presence of finite precision arithmetic errors. The implementation of complex digital control ...
