Latest Patents
Samuel holds a patent for "High speed control of motor current in a distributed inverter system." This invention addresses systems, devices, computer-implemented methods, and computer program products that facilitate optimized control of an electric motor using a smartcell battery system. The system employs a central controller that wirelessly communicates with local controllers connected to clusters of battery cells. These clusters are configured to generate a three-phase current output to control motor torque. The central and local controllers perform a main control loop to manage the three-phase current output with an update frequency of about 1 kHz. Additionally, a local control loop with an update frequency of about 10 kHz is implemented by the local controllers to detect and minimize disturbances in motor operation using estimated local control information.
