英文摘要： “Non-sinusoidal Oscillation Generator for Continuous Casting Mold Driven by Servo Motor” was validated and authorized as a invention patent by the State Intellectual Property Office in 2007. This invention not only can avoid some shortages that exist in other existing devices, but also has some advantages, such as save energy and reduce consumption, have long performance life, etc.. On condition that hold self-owned intellectual property and have some devices in laboratory, the applicants want to develop a Management-Control Integration System of Non-sinusoidal (Sinusoidal) Oscillation for Continuous Casting Mold Driven by Servo Motor, do experiment and industrial application test, and do research on some key technologies of the system. The main research includes: 1) Integration design of the system and trial manufacture of the device. 2) Research on high precisely rotate-speed/ position tracking control of servo motor, and the smooth switching between position control when servo motor starts or stops and rotate-speed control during normal working. 3) Research on velocity or displacement tracking control algorithm of mold. 4）Design of simulation vibration table and its shock absorption for Continuous Casting Mold. 5) Research on real-time, accurately, smoothly switching control among different non-sinusoidal osc
