Patent number: 11913512Abstract: A vibration suppression method for a servo motor and a load multistage drive system is provided. For a number N of fixed vibration frequencies and one vibration frequency varying with a load position existing in a multistage drive mechanism, a number of N+1 vibration suppression filters are adopted, and each filter is configured to eliminate a corresponding vibration frequency. Fixed vibration frequencies and a vibration frequency varying with a load position in a multistage drive system are measured by using an offline method, and the varied vibration frequencies are made into a two-dimensional table related to the load positions. The fixed vibration frequencies are eliminated by using fixed-frequency parameter vibration suppression filters; and the varied vibration frequencies are eliminated by using a variable-frequency parameter vibration suppression filter, and the vibration frequencies are obtained in real time according to the load positions and the two-dimensional table.Type: GrantFiled: May 13, 2019Date of Patent: February 27, 2024Assignee: NANJING ESTUN AUTOMATION COMPANYInventors: Renkai Fan, Kaifeng Yang, Dandan Qi, Wei Qian, Bo Wu

Patent number: 11062090Abstract: A method and apparatus for mining general text content, a server, and a storage medium, are disclosed. A specific embodiment of the method can include: acquiring a question including a target subject and a target characteristic; and inputting the target subject, the target characteristic and a target text into a pre-constructed answer prediction model, and determining a starting position and an ending position of an answer to the question in the target text by the answer prediction model. The answer prediction model is pre-trained based on a sample question including a sample subject and a sample characteristic, and a starting position and an ending position of a sample answer in a text. In the technical solution provided by the embodiments of the present disclosure, the starting position and the ending position of the answer in the target text may be correctly predicted, thereby increasing the accuracy of answer recognition.Type: GrantFiled: December 7, 2018Date of Patent: July 13, 2021Assignee: Beijing Baidu Netcom Science and Technology Co., Ltd.Inventors: Renkai Yang, Hao Wang, Ying Li, Yilin Zhang
