belt conveyor is a typical energy conversion system from electrical energy to mechanical energy. Its energy efficiency can be divided into four components: performance efficiency, operation efficiency, equipment efficiency, and technology efficiency [7]. The monitoring and control of conveyor systems is studied in several papers [2, 3, 5, 6]
The condition [χ]1 (t,0) = 0 means that, if there is no source of material receipt, i.e. λ(t) = 0, then the material flow at the conveyor belt input is zero. If the section ∆Sm corresponds to the m-th technological operation of the production line, then equations (10), (11) determine the state of the interoperational stocks before the m-th technological operation.
the optimal speed control algorithm and changeover of production operations is limited to 30 minutes (Figure 3). This imposes a strong constraint on the choice of conveyor system models used to design conveyor belt speed control systems. 2. Formal problem statement
