In this paper the application of the model predictive control (MPC) technique for controlling the speed of the induction motor drive has been presented. Vector control principle has been used for decoupling between motor speed and rotor flux. A simple model of induction motor is employed in the MPC structure so as to minimize the computational load. The MPC controller design is taken into account the effect of uncertainty due to motor parameters variation and load disturbance could be reduced. The effectiveness of the proposed scheme has been successfully verified through simulations. The performance of the system including the MPC controller is compared with the corresponding one using the traditional PI controller. The results proved that the induction motor with the MPC speed controller has superior transient response, and good robustness in face of uncertainties including load disturbance. Moreover, accurate tracking performance has been achieved.

The burning of petroleum gas as fuel in simple burners under field conditions as a rule occurs in the detonating regime with low efficiency coefficient and is accompanied by incomplete gas combustion and a considerable emission of pollutants into the atmosphere. The use of an adsorption unit with zeolite filler as a part of fuel pre-burning preparations proposed as a solution to this problem. This paper presents data and information on the application of an adsorption unit in electric power installations for the pre-burning preparation of associated gas in locations of petroleum production. A comparative analysis of the associated gas used before and after the adsorption unit is also described. Methods of research on the effectiveness of the adsorption unit are to determine the service life of zeolite filter depending on the amount of regeneration and time of work in the given conditions. Adsorption unit will clean the gas from heavy hydrocarbons, dry and level out the differences in the composition of the gas associated with the changes in ambient temperature.

In the given article, on the basis of the standard hydrodynamic representations, the physical model of the directed destruction of metals by cutting is offered. Process of cutting of metals is considered as process of the directed destruction, i.e. process of deep plastic deformation of metal always led up to destruction on surfaces of the cutting, defined by process kinematics. The design of the metal-cutting tool for part removal liquid-alloy (in the form of a ridge) from an internal contact zone of shaving is presented. Physicomechanical properties of ridges both their geometrical form and the sizes testify that they are formed of a stream of the melted metal owing to fast cooling in environment. Identity of mechanical properties of ridges and the modified layer on a tool surface of shaving testify to identity of conditions of their formation from liquid metal. The experimental evidence of the offered physical model is produced.

Knowledge-Based Neural Network (KBNN) model is one of the most useful methods which is used to predict every single variability to perform the parameters on data of the Roll forming (RF) process. It is true that the quality of product and the parameters in RF process depend on the reliability of the training in KBNN. To achieve this, the new novel of the optimal algorithm including integration between Genetic Algorithm (GA) and Hill climbing Algorithm (HCB) was proposed to train the KBNN model. Initially, the GA is applied to find the local optimal region, then, the HCB will detect the best location area in which the training error of the KBNN model is less than 8%. In addition, the Finite Element Analysis (FEA) results of the high fidelity FE model were used to obtain the trained data set of the KBNN model. From simulation results, it can be concluded that the efficiency of the proposed method is higher than that of the conventional methods in optimization of the RF process.

A new approach in the development of advanced coating deposition and ion implantation method including an application of filtered dc metal plasma and high-frequency short-pulsed negative bias voltage with a duty factor in the range 10%-99% are considered. The ion energy spectrum for different negative bias potential pulse duration (120-1100) ns was measured. The map of different methods of ion beam and plasma material treatment using high-frequency short pulse metal plasma immersion ion implantation or deposition depending on bias pulse duty factor and amplitude for Cu plasma is presented. The ion assisted coating deposition depending on samples conductivity and thickness, plasma concentration, pulse repetition rate and amplitude and duty factor has been examined.

An innovative concept in the development of advanced coating deposition and ion implantation method including an application of filtered DC metal plasma source and high-frequency short-pulsed negative bias voltage with a duty factor in the range 10 ÷ 99% are considered. The regularities of ion implantation and metal plasma deposition for dielectric samples are theoretically and experimentally investigated. Experimentally has been shown that metal plasma based ion implantation as well as high-concentration metal plasma ion implantation with compensation of ion surface sputtering by metal plasma deposition as well as ion-assisted coating deposition can be realized by variation of bias potential ranging from 0 V to 4 kV, pulse repetition rate smoothly adjusted in the range (2 ÷ 4.4)×105 p.p.s. and pulse duration ranging from 0.5 to 2 μs. Special features of the material treatment method depending on plasma concentration, pulse repetition rate and duty factor has been examined.
