Special Issue Information

Dear Colleagues,

The development of digitalization of processes and systems has been going on continuously for decades. New technologies such as artificial intelligence, cloud computing, and the Internet of Things, present in Industry 4.0 standards, have led to an unprecedented development of control and intelligent systems. Advancing automation of systems and processes is pushing the boundaries of what is possible in many technology areas through the use of artificial intelligence. Intelligence is also implemented within smart grid technology. Such an architecture simplifies the control of network operation, automates the grid, and provides the tools needed to manage energy demand and integrate distributed generation sources.

This Special Issue is devoted to intelligent systems that improve the control of nonlinear systems, including multidimensional systems. Topics covered in this Special Issue include intelligent sensing and actuation systems, intelligent system and process controllers, and energy distribution control systems. I would like to invite authors dealing with the subjects of this Issue to share the latest research, developments, and new trends they have observed.

This article presents a neural algorithm based on Reinforcement Learning for optimising Linear Quadratic Regulator (LQR) creation. The proposed method allows designing such a target function that automatically leads to changes in the quality and resource matrix so that the target LQR regulator achieves the desired performance. The solution’s stability and optimality are the target controller’s responsibility. However, the neural mechanism allows obtaining, without expert knowledge, the appropriate Q and R matrices, which will lead to such a gain matrix that will realise the control that will lead to the desired quality. The presented algorithm was tested for the derived quadrant model of the suspension system. Its application improved user comfort by 67% compared to the passive solution and 14% compared to non-optimised LQR. Full article

There is tremendous potential in solar energy to meet future electricity demands. Partial shading (PS) and drift are two major problems that must be addressed simultaneously to achieve the maximum power point (MPP) of a stand-alone PV system, which are discussed in this paper. Both of these factors contribute to the voltage drop due to heavy steady-state oscillation. The partial shading and drift problem are associated with severe rapid changes in the insolation. A modified drift-control perturbation and observation DC-(P&O) approach was investigated using a low-cost programmable hardware solution, i.e., the ARM Cortex M4 32-bit Microcontroller (MC) (STM32F407VGT6), with efficient embedded programming and Waijung block sets for real-time solutions. The experimental setup was accomplished on a 40-watt solar panel. It was found that the proposed method had a significant impact on drift control during abrupt changes in current and voltage caused by shading effects, with the controller conversion efficiency of 80.39% and 94.48% with percentage absolute errors of 7.3 and 7.2 for cases with and without PS and drift, respectively.
