Cycling induced performance degradation of flash EEPROMs has been reported for V/sub B/=0 and V/sub B/<0 programming operation. Compared to V/sub B/=0, V/sub B/<0 programming shows lower interface degradation for identical cumulative charge fluence (for program) during repetitive program/erase cycling. Reduction in programming gate current has been found to be lower for V/sub B/<0 operation under identical interface damage as the V/sub B/=0 case. As a consequence, programming under VB<0 condition has been found to cause lower degradation of programming time and programmed V/sub T/ due to cycling.

We present a new subdivision strategy in interval analysis for computing the ranges of functions. We show through several real-world examples that the proposed subdivision strategy is more efficient than the widely used uniform and adaptive subdivision strategies of Moore (Methods and Applications of Interval Analysis, SIAM, Philadelphia, 1979).
In this paper we present a new algorithm for discrete sliding mode control of linear multivariable systems using fast output sampling feedback. Here we make use of a single switching surface regardless of the number o...

In this paper we present a few controllability properties of a three link planar, horizontal underactuated manipulator with three revolute joints (3R) and two control inputs. The controllability analysis is presented for various actuator configurations. In particular, it is shown that the system is small time locally controllable (STLC) for all except one of the configurations.

Power System Stabilizer (PSS) are added to excitation system to enhance the damping of electric power system during low frequency oscillations, Design of decentralized PSS for 4 machines with 10 buses using periodic output feedback is proposed. The nonlinear model of multi-machine system is linearized and linear state space model is obtained. An output injection gain is obtained using LQR technique. A decentralized periodic output feedback gain which realizes this output injection gain is obtained using LMI approach. This method doesn't require state of the system for feedback. It uses only the output for feedback. Thus it is easily implementable.
This paper explores the relationship between the feedback linearization and the continuous time predictive control as applied to the state tracking problem of rigid link manipulators. It is shown that the predictive c...

This paper presents the controller synthesis and real-time simulation of the final net-recovery phase of a remotely piloted vehicle (RPV). The recovery configuration imposes certain requirements on the controller. Further, the inherent geometry and structure of the aircraft impose restrictions on certain state variables. The mixed H/sub 2//H/sub /spl infin// approach was adopted to synthesize the controller. The synthesized controller was discretized using standard techniques; a real-time simulation was then conducted using the detailed model of the RPV on a stand alone DSP device and the controller hooked up to the DSP through a PC.
