Latest Patents

One of his latest patents is the "Servo actuator and fast self-tuning method of gain for using the same." This invention discloses a fast self-tuning method of gain applied to a servo actuator connected with a motor. The method includes several steps, such as retrieving current-feedback information of the motor to compute a torque estimated value and retrieving position-feedback information to compute an acceleration estimated value. The system inertia is then computed based on these values, which indicates the inertia of the motor carrying a specific load. An estimated control gain for the servo actuator is computed based on the system inertia, followed by a self-tuning procedure performed by the servo actuator in accordance with the estimated control gain.

Another significant patent is the "Ultrasonic drive and driving method." This invention provides an ultrasonic drive and driving method configured for driving an ultrasonic tool. The ultrasonic drive includes a switch module, a sensing element, and a control element. The sensing element senses the voltage and current of the ultrasonic tool and generates a sensing signal accordingly. The control element receives this sensing signal and outputs a control signal, while the switch module outputs an ultrasonic signal according to the control signal for controlling the vibration of the ultrasonic tool. The drive operates a frequency sweep function and a frequency following function, adjusting the operating frequency to keep the impedance of the ultrasonic tool consistent.
