This invention discloses a weighing adaptive vibration control system and method, belonging to the field of weighing technology. The invention collects vibrator state information, weighing sensor output signals, sliding mode surface values, errors, and their derivatives. Then, based on the system dynamics model and control objectives, the sliding mode surface form and control law are determined. Simultaneously, a neural network multilayer perceptron structure is employed. The input layer receives the sliding mode surface values, errors, and their derivative signals; the hidden layer processes the input information through nonlinear transformation and feature extraction; and the output layer outputs the switching gain and sliding mode surface coefficients. Finally, the neural network is trained using an online learning algorithm. During system operation, based on the output error of the weighing sensor, the neural network weights and biases are adjusted using an optimization algorithm to continuously optimize the sliding mode controller parameters. The sliding mode controller generates precise control signals based on the optimized parameters to accurately control the vibration of the vibrator, achieving efficient and stable operation of the weighing process under vibration interference and improving weighing performance.

This utility model provides a prefabricated staircase installation component, including a transverse tread and a longitudinal connecting plate. The transverse tread has a first connecting structure at both its front and rear ends, symmetrically arranged along the center of the transverse tread. The longitudinal connecting plate has a second connecting structure at both its upper and lower ends, symmetrically arranged along the center of the longitudinal connecting plate. The second connecting structures are slidably connected to the first connecting structures. A support structure is fixed between the bottom of the transverse tread and the rear of the longitudinal connecting plate. By using modular transverse treads and longitudinal connecting plates, the staircase can be assembled on-site using the first and second connecting structures, avoiding the transportation and installation limitations caused by the large size of the prefabricated staircase. Installation is more convenient and faster. Furthermore, the support structure between the transverse tread and the longitudinal connecting plate effectively improves the strength and load-bearing capacity of the staircase.
