Special Issue Information

Dear Colleagues,

Nowadays, Automation that integrates Artificial Intelligence techniques is the new paradigm of processes control. A very large number of papers describe applications and theoretical studies that use artificial intelligence techniques for all the aspects that involve nonlinearities or imprecise, incomplete, uncertain knowledge. That is why the Metaheuristic Algorithms (MAs), such as Genetic Algorithm, Simulated Annealing, Particle Swarm Optimization, Ant Colony Systems, and many others, are good options to solve optimization problems that involve a big computational complexity.

Smart sensors have onboard capabilities to tackle self-diagnostics, self-identification, and self-adaptation tasks that sometimes involve difficult optimization problems. Optimizing sensor deployment for multi-sensor systems, human activity recognition, data fusion models are also known applications where the MAs can be useful. Lately, the new "structure as a sensor" paradigm can entail multicriteria optimization problems with multimodal objective functions. Structural health monitoring uses a dense array of sensors that can lead to such a problem.

Especially the ability to cope with nonlinearities and the lack of smoothness properties renders the MAs' use an effective and at hand approach. Moreover, the implementation can be made straightforwardly, and a near-optimal solution is always available.

For the confirmed scholars working in this domain, this special issue will be a good opportunity to present the different facets of using the MAs: approaches, ideas, new techniques, and applications. In the same time, the lecturers that are newcomers in this framework will have an instructive image concerning the MAs.

This special issue is focused more on automation. Papers focus on sensors may choose our joint Special Issue in Sensors (ISSN 1424-8220, IF 3.275).

The closed-loop optimal control systems using the receding horizon control (RHC) structure make predictions based on a process model (PM) to calculate the current control output. In many applications, the optimal prediction over the current prediction horizon is calculated using a metaheuristic algorithm, such as an evolutionary algorithm (EA). The EAs, as other population-based metaheuristics, have large computational complexity. When integrated into the controller, the EA is carried out at each sampling moment and subjected to a time constraint: the execution time should be smaller than the sampling period. This paper proposes a software module integrated into the controller, called at each sampling moment. The module estimates using the PM integration the future process states, over a short time horizon, for different control input values covering the given technological interval. Only a narrower interval is selected for a ‘good’ evolution of the process, based on the so-called ‘state quality criterion’. The controller will consider only a shrunk control output range for the current sampling period. EA will search for its best prediction inside a smaller domain that does not cause the convergence to be affected. Simulations prove that the computational complexity of the controller will decrease.

Optimal control problems can be solved by a metaheuristic based algorithm (MbA) that yields an open-loop solution. The receding horizon control mechanism can integrate an MbA to produce a closed-loop solution. When the performance index includes a term depending on the final state (terminal penalty), the prediction’s time possibly surpasses a sampling period. This paper aims to avoid predicting the terminal penalty. The sequence of the best solution’s state variables becomes a reference trajectory; this one is used by a tracking structure that includes the real process, a process model (PM) and a tracking controller (TC). The reference trajectory must be followed up as much as possible by the real trajectory. The TC makes a one-step-ahead prediction and calculates the control inputs through a minimization procedure. Therefore the terminal penalty’s calculation is avoided. An example of a tracking structure is presented. The TC may also use an MbA for its minimization procedure. The implementation is presented in two versions: using a simulated annealing algorithm and an evolutionary algorithm. The simulations have proved that the proposed approach is realistic. The tracking structure does or does not work well, depending on the PM’s accuracy in reproducing the real process. Full article
