Witryna18 lip 2024 · This paper presents a novel observer-based control scheme for a DC-DC boost converter system using the Lyapunov stability theorem by considering input saturation. To estimate the unavailable state or parameter, a new approach called Immersion and Invariance (I&I) is employed. According to this method, two … Witryna8 cze 2024 · The immersion and invariance (I&I) observer is used to estimate the load torque and speed of the BLDC motor. At the time of starting, the motor rotates in arbitrary direction, and sometimes, because of the cogging action, it may take a huge current. Therefore, a new start-up method is proposed for the BLDC motor, which maintains …
