A class of discrete-time networked switched control systems are investigated with event-triggered control. The closed-loop system is formulated as switched linear systems with time-varying delays, based on which the exponential stability conditions are obtained under the time delay system framework. The co-design conditions of the control gain and the triggering parameters are proposed. Finally, a...
This paper reports a high-frequency DC-DC boost converter capable of sustaining up to 4 the rated process voltage using high-voltage devices fabricated in standard 0.13 1.2 V CMOS without additional masking steps. Integrated Schottky Barrier Diodes (SBD) and high-voltage stacked composite NMOS switches enable processing of large voltages in a 100 MHz digitally assisted four-phase...
Electronic safety and arming system is the most advanced safety and arming system of fuze. And it has been widely used in many various kinds of missiles. Owing to the continuous breakthroughs in FPGA technology for decades, the performance of FPGA products becomes much better. This gives birth to a novel realization of electronic safety and arming system. In this paper, such a system based on FPGA...
On the basis of the Inverse System theory and Fuzzy Sliding Mode Control, this paper studies on Dynamic Decoupling Control of permanent magnet synchronous motor (PMSM), and a new sliding mode control strategy of fuzzy reasoning has been presented. According to the dynamic mathematical model of PMSM's speed regulation system, the existence of its inverse system is proven, and the design method of fuzzy...
Permanent magnet type bearingless motor is nonlinear and coupling complex system. On the basis of the complete mathematical model which express the coupling between suspension and rotor torque, and under variation of Interference and Processing Parameters, this paper discussed the effects of the motor' parameters on the operation speed and suspension performance. Meanwhile, aiming at the robust control...
A 100 MHz digitally assisted 4-phase switched-inductor boost converter delivers 240 mW to load voltages of 3 to 5 V with peak efficiency of 64%, and a 45 MHz hybrid switched-inductor/capacitor boost converter delivers 20 mW over a 6 to 10V output range at peak efficiency of 37%. Implemented in a standard 1.2 V 0.13 μm CMOS, the converters use integrated schottky diode rectifiers with 10 V blocking...
