Abstract

Ensuring the flatness of the scraper conveyor is essential for drum height adjustment. However, there have been no studies on drum height adjustment based on floor distortion. Therefore, a continuous adjustment compensation strategy based on floor distortion is proposed. First, the mechanism and influence of floor distortion are analyzed using dynamic simulation software. Subsequently, a mathematical model for the drum height adjustment is developed, and an SMC controller is designed. The response time and tracking capabilities of the system are validated using three typical signals. Finally, a co-simulation platform integrating RecurDyn, AMESim, and Simulink is constructed to enable real-time adjustments of the drum height and traction speed. Simulation results indicate that the maximum absolute error and average absolute error are 6.23 mm and 2.59 mm, respectively, with a velocity of 20 m/min, demonstrating the achievability of the proposed continuous adjustment compensation strategy based on floor distortion.

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
