  • A Comparative Study of Fuzzy SMC with Adaptive Fuzzy PID for Sensorless Speed Control of Six-Phase Induction Motor

    Publication

    - Year 2022

    Multi-phase motors have recently replaced three-phase induction motors in a variety of applications due to the numerous benefits they provide, and the absence of speed sensors promotes induction motors with variable speed drives. Sensorless speed control minimizes unnecessary speed encoder cost, reduces maintenance, and improves the motor drive’s reliability. The performance comparison of the fuzzy sliding mode controller (FSMC)...

    - Year 2004

    W pracy przedstawiono elektryczne i optyczne właściwości niedomieszkowanego i domieszkowanego Sr SmCoO3 cienkich filmów. Gęste i przezroczyste filmy o grubościach 80-100nm były przygotowane na szafirze metodą nanoszenia wirowego ciekłych polimerów. Filmy były syntezowane w temperaturach od 500 do 800C co umożliwiło otrzymanie różnych mikrostruktur. Elektryczne właściwości filmów były mierzone w funkcji temperatury. Domieszkowanie...

  • DIGITAL HYDRAULICS CIRCUIT BASED ON PWM FUNCTION FOR CONTROLLING HYDRAULIC ACTUATOR POSITION

    Publication

    - Year 2022

    Hydraulic systems are used in many different industries, such as multi-source hydrostatic drive systems. In traditional hydraulic systems, a proportional servo valve is used to control the position of hydraulic actuators. The low energy efficiency and high cost of these control valves are two major problems with these systems. Digital hydraulics is one of the most unique ideas on how to solve these problems. Researchers like digital...

  • A New Fuzzy Sliding Mode Controller with PID Sliding Surface for Underwater Manipulators

    Publication

    Design of an accurate and robust controller is challenging topic in underwater manipulator control. This is due to hydrodynamic disturbances in underwater environment. In this paper a sliding mode control (SMC) included a PID sliding surface and fuzzy tunable gain is designed. In this proposed controller robustness property of SMC and fast response of PID are incorporated with fuzzy rules to reduce error tracking. In the control...
