  • Patent number: 11467545
    Abstract: The disclosed systems and techniques enable dual mode operation for model-based controllers in which the controllers are capable of operating in both (i) a constrained solution mode, and (ii) an unconstrained solution mode. The dual mode operation improves control because it enables the use of constrained solution mode operation when possible (constrained solution mode often enables superior control) and enables the use of unconstrained solution mode when constrained solution mode is not possible (e.g., when it is impossible to develop the constrained solution with the time available). This enables superior control when compared to typical model predictive control (MPC) controllers.

  • Patent number: 11378939
    Abstract: A method automatically controls stores for a processing line for containers pre-dosed with fluid products. The identifying code for each container is determined and then checked whether the container is necessary for production orders received. The container is introduced into a first store and the quantity and identifying codes of the containers in the first store are recorded. Production orders are checked for products yet to be started. The containers are picked up and sent towards a first manipulation station and at least one production order of a product is processed and the containers are sent towards different stations. Quality control inspection is conducted and if the product is compliant, introduced into a second store. Containers with non-compliant product are introduced into a control line.
