Position Control of Hydraulic Actuators Using Fuzzy Pulse Width Modulation (PWM)
Applied Mechanics and Materials, 2015Hydraulic actuators are widely employed for industrial automation for its high power over weight ratio, functionality in tough operating conditions and low cost. However, the dynamics of hydraulic systems are non-linear and the system subjected to non-smooth and discontinuous non-linearities due to directional change of valve opening, friction, valve ...

2018 International Seminar on Application for Technology of Information and Communication, 2018
High torque and high efficiency are two factors used as a consideration of why many electric vehicles (EV) use brushless DC motor (BLDCM) as a propulsion system. Likewise, Amtenar car -a PENS's electric car- use this kind of motor as its propulsion. BLDCM can be driven by two techniques.

Energy Regenerative Damper Using Pulse Width Modulated (PWM) Step-up Chopper
Volume 6: International Symposium on Motion and Vibration Control, 1999Abstract This paper describes a new technique of improving the efficiency of an energy regenerative damper. It is intended for an electro-dynamic type vibration damper to regenerate vibration energy efficiently. Normally regenerative damper can regenerate vibration energy only at high speed motion.

A new pulse-width modulation (PWM) scheme for modular structured multilevel voltage source inverter
International Journal of Electronics, 2004This work proposes a new switching scheme for a particular multilevel topology, known as the modular structured multilevel inverter (MSMI). The proposed scheme is based on symmetric regular sampled unipolar PWM, with multiple modulating waveforms and a single carrier. Mathematical equations that define the PWM switching instants are derived.

RELIABILITY TESTS OF PULSE WIDTH MODULATION (PWM) VALVES FOR FLOW RATE CONTROL OF ANHYDROUS AMMONIA
Applied Engineering in Agriculture, 2005Pulse-width-modulation (PWM) offers the potential to improve anhydrous ammonia application accuracy and control. The solenoid valve used in the manifold is central to the PWM metered anhydrous ammonia applicator. Valve durability plays a major role in acceptance by the farmers and provision of warranty by the manufacturer.
