A combination of identification and control procedures is presented which is aimed at precise control of systems with any value of time delay. Suggested strategy allows the predictive controller to adapt its parameters to a value of the time delay identified during the control process. The system flexibility resides in the ability to work precisely even with time-delay values that are not integer multiples of the sampling period. Overall, the designed approach presents a more precise method to control systems with both static and variable cases of time delay.

The Mathematical Model

Aimed at the puzzle of the pollutant degradation of sewage treatment in technics of SBR being difficult to implement the mathematical modeling and precise control, the paper researched on the modeling and control of the aeration process in sewage treatment. In the paper, it pointed out the technical difficulties existed in pollutant degradation control, analyzed the cybernetics characteristic in pollutant degradation process, built the mathematical model of control process based on the mechanism of biochemical reaction, proposed the control strategy matched with the cybernetics characteristic of aeration process, constructed the control algorithm based on human simulate intelligence. Taken the built process control model as an example, the simulation experiments demonstrated the feasibility and effectiveness of proposed control strategy. The research results show that the built model and proposed control strategy are feasible and applicable.

One of the most significant issues in exercising command and control is the implementation of such methods and procedures that could enable the most effective use of field artillery capabilities. One of these methods is targeting. This process has been implemented in the Command and Control Procedures of the Polish Armed Forces for several years.This article focuses on the targeting process in the Land Forces. Special attention is paid to the functions involved in this process and its significance in the command and control process. Assuming that in the near future the implementation of this process will become fact, a number of organizational and procedural arrangements in field artillery will have to change. Therefore, the article mainly attempts to determine the impact of targeting on specific aspects of the command and control of field artillery in order to identify problem areas where these changes may be necessary. As a result, the focus is on the decision problems solved as part of targeting and organizational considerations.

And Control

In the paper, a comparative case study covering different control strategies of unstable and nonlinear magnetic levitation process is investigated. Three control procedures are examined in order to fulfill the specified performance indices. Thus, a dedicated PD regulator along with the hybrid fuzzy logic PID one as well as feed-forward neural network regulator are respected and summarized according to generally understood tuning techniques. It should be emphasized that the second PID controller is strictly derived from both arbitrary chosen membership functions and those ones selected through the genetic algorithm mechanism. Simulation examples have successfully confirmed the correctness of obtained results, especially in terms of entire control process quality of the magnetic levitation system. It has been observed that the artificial-intelligence-originated approaches have outperformed the classical one in the context of control accuracy and control speed properties in contrary to the energy-saving behavior whereby the conventional method has become a leader. The feature-related compromise, which has never been seen before, along with other crucial peculiarities, is effectively discussed within this paper.

Different Levels

This study assessed the effects of Methylcellulose (MC) at different concentrations on plant-based meat analog (PBMA) patties, comprised of commercial texture vegetable protein (C-TVP) and textured isolate soy protein (T-ISP) as key ingredients, and compared to beef patty control. A significantly higher difference was observed in moisture content in control with increasing MC concentration than the C-TVP and T-ISP patties. However, protein varied significantly among three different protein sources, with control had higher protein content than PBMA patties. Crude fiber content recorded higher values in C-TVP as compared to control. Significantly lower pH values were recorded in control than C-TVP and T-ISP respectively. Regardless, with the addition of MC or ingredient PBMA and control patties tend to reduce lightness (L*) and redness (a*) value after cooking. Although control sample before cooking exhibits lighter and redder than PBMA patties (C-TVP and T-ISP). Likewise, water holding capacity (WHC) decreases as the concentration of MC increases (1.5–4%) in control and PBMA patties. Warner-Bratzler shear force (WBSF) and texture profile analysis (TPA), including hardness, chewiness, and gumminess of control, were significantly higher than C-TVP and T-ISP. Consequently, panelists’ in the sensory analysis presented that C-TVP patties containing 3% of MC had better sensory properties than T-ISP. Hence, PBMA patties with C-TVP and incorporation of 3% MC are considered ideal for manufacturing of meat analog as related to control (beef).
