Tourism is a beautiful thing, tourism can bring tourists variety of enjoyment and experience, let harvest instant joy happiness, leave them with good impressions memories, so that are relaxed soothed, actually way life. As industry has developed rapidly after the epidemic in China, “micro-vacation” increasingly become first choice for people’s daily travel. This paper combines customer position...

At the field of nanometer positioning and machining, high-precision tracking is a key technology micro-positioning platform which driven by voice coil motor. To improve accuracy response speed, sliding-mode active disturbance rejection control proposed. The mathematical model system established, in perturbation spring-damping force are set as unknown terms, an extended state observer used to es...

Based on the superiority of piezoelectric elements, including lightweight, high electric mechanical transformation efficiency and a quick response time, piezoelectric-based micro-positioning actuator is developed in this investigation. For eliminating effects hysteresis modeling uncertainties that appeared actuator, nonlinear adaptive fuzzy robust control design with perturbation cancellation a...
