Special Issue Information

Dear Colleagues,

The design and analysis of traditional control systems is based on accurate system mathematical models. However, practical processes are complex, nonlinear, and time varying. It is generally impossible to obtain an accurate mathematical model due to the uncertainties. For the actual system, it is often necessary to put forward and follow certain harsh linearization assumptions, which are often inconsistent with the reality in application. Moreover, some complex and uncertain control objects cannot be described by the traditional mathematical model, which makes traditional model-based control methods invalid. There is a paradox in that the actual control task is complex, while the traditional control task has low requirements and cannot reduce complexity.

In recent years, with the rapid development of artificial intelligence, robotics, advanced manufacturing, power systems, aerospace, and other fields, traditional control methods cannot meet their requirements of complex dynamic processes. Therefore, a variety of advanced intelligent control methods, such as fuzzy control, data-driven control, neural network control, and learning control, have emerged and achieved successful applications.

The main aim of this Special Issue is to seek high-quality submissions that highlight emerging theories and applications with advanced nonlinear intelligent control and address recent breakthroughs from theoretical and practical aspects.

The topics of interest include but are not limited to:

  • Fuzzy control;
  • Neural network control;
  • Reinforcement learning;
  • Model-free control;
  • Data-driven control;
  • Nonlinear intelligent control: theory and applications;
  • Intelligent control algorithms and their applications in power system, robotics, unmanned vehicles, etc.

A moving mirror control system of the Fourier transform spectrometer (FTS) based on the feedforward inputs obtained by the intelligent algorithm is proposed in this paper. Feedforward control is an important part of the moving mirror speed control system of the FTS. And it is always difficult to quantitatively calculate the feedforward inputs through a precise mathematical model of the controlled object. Therefore, based on the expected motion law, an intelligent adaptive algorithm for obtaining feedforward inputs of the moving mirror system was designed. The algorithm decomposed the motion stroke into several position points, iteratively obtained the driving quantity of the moving mirror that met the expected instantaneous speed of each position point, and finally obtained the feedforward inputs of the whole motion stroke. The feedforward inputs obtained by the intelligent algorithm combined with the speed loop PID control constitute the complete moving mirror speed control system. Then, we applied the control system to the moving mirror of the FTS and acquired the velocity of the moving mirror. The experimental results show that the control system is feasible, the error of the peak-to-peak velocity is 0.047, and the error of the root mean square (RMS) velocity is 0.003. Compared with the single-speed-loop control system without feedforward inputs, the error of the peak-to-peak velocity is reduced by 43.3%, and the error of the RMS velocity is reduced by 67.7%, realizing a more accurate control of the moving mirror. Therefore, the control system based on the feedforward inputs obtained by the intelligent algorithm is a feasible and effective moving mirror speed control scheme of the FTS. Full article
