Abstract: The present invention discloses a networked control system (NCS) time-delay compensation method based on predictive control. The method comprises the following steps: (1) acquiring random time-delay data in an NCS, and preprocessing the data; (2) predicting the current time-delay by using a fuzzy neural network (FNN) optimized by a particle swarm optimization (PSO) algorithm; (3) compensating the predicted time-delay by using an implicit proportional-integral-based generalized predictive control (PIGPC) algorithm; (4) determining whether a preset work end time is up according to a clock in the NCS; if yes, ending the process; if no, returning to step (2). The method disclosed by the present invention can accurately predict and effectively compensate the NCS time-delay and has excellent development prospect.

Abstract: A method and device for separating and recovering heavy metal ions through membrane-forming mineralization fixation, applicable in the domain of acid wastewater treatment containing heavy metal ions. The process involves mixing composite mineral particles with heavy metal acidic wastewater, then conducting a first hydration reaction under static conditions. This leads to adsorption, precipitation, and crystallization of heavy metal ions in the wastewater via a colloidal liquid membrane, resulting in particles coated with a mineralized membrane. These particles exhibit a gap between the mineralized membrane and their core. The next step is to separate these coated particles and recover them. The preparation of composite mineral particles involves mixing sodium carbonate/sodium silicate, bentonite, carbide slag, and water, followed by a second hydration reaction and subsequent granulation, aging, and dehydration condensation. The particle sizes of both bentonite and carbide slag are maintained at ≤74 m.
