Global Optimal Realizations of Fixed-Point Implemented Digital Controller with the Smallest Dynamic Range
A novel approach is proposed to design optimal finite word length (FWL) realizations of digital controllers implemented in fixed-point arithmetic. An analytical method is first formulated to obtain a global optimal controller realization that optimizes an FWL closed-loop stability measure. Since this FWL closed-loop stability measure is solely linked to the fractional part or precision of fixed...
متن کاملImproved Closed-loop Stability with Fixed-point Control Law Implementation Using the Delta Operator
A stable discrete-time control system may become unstable when the discrete-time control law is implemented with a xed-point digital control processor (DCP) due to the nite word length (FWL) eeects which depend on the control law structures and the discrete-time representations (e.g., delta operator or forward-shift representations) used to represent the control laws. To improve closed-loop sta...
متن کاملVerification of fixed-point digital controllers using direct and delta forms realizations
The extensive use of fixed-point digital controllers demands a growing effort to prevent design errors that appear in the discrete-time domain. The present article describes a novel verification methodology, which employs Bounded Model Checking (BMC) based on Satisfiability Modulo Theories (SMT) to verify the occurrence of the design errors, because of the finite word-length (FWL) format, in fi...
متن کاملFinite Word Length Implementation for Digital Reduced Order Observer Based Controllers
Implementation issues for digital reduced-order observer-based controllers with Finite Word Length (FWL) considerations is studied. A tractable FWL stability related mesure is derived, and the optimal FWL realization problem for digital reduced-order obverserbased controller is to find those realizations that maximize this related measure. This optimization problem is formulated as an unconstra...
متن کاملOptimal Realizations of Floating-Point Implemented Digital Controllers with Finite Word Length Considerations
The closed-loop stability issue of finite-precision realizations is investigated for digital controllers implemented in floating-point arithmetic. Unlike the existing methods which only address the effect of the mantissa bits in floating-point implementation to the sensitivity of closed-loop stability, the sensitivity of closed-loop stability is analyzed with respect to both the mantissa and ex...
