The last twenty years have seen a radical step-change in the capability and application of Control Engineering, brought about by advances in computational speed and capacity. Control design for contemporary, complex engineering systems has developed alongside Computer Aided Control System Design, powerful real-time embedded computation, and both off-line and on-line optimization techniques.
This Special Issue will bring together papers, which particularly describe recent advances in Control Engineering in industrial applications and complex engineering systems, describing the application of novel theory across all areas of Automation. Papers which include practical experimental results are particularly encouraged, as are papers which set Control advances in the wider context of, for example, society, economics, energy and environment.
Application topics might include:
Electrical Power Systems(including Renewables and Smart Grid)
Manufacturing and Process Control
Control Theory topics might include:
Artificial Intelligence and Heuristics
Optimisation and Search
Non-linear, Adaptive and Robust Control
Advances in PID
Model based Control
Fault Detection and Diagnostics

Title: pCAMAL: A Cognitive Control Architecture

Abstract: Evolution has presented us with a wide range of efficient ecological control architectures. We conveniently refer to these as minds. The study of these biological control architectures has informed artificial intelligence, cognitive science and related disciplines on a number of levels. The technologies arising from these investigations have given rise to a diverse range of machine intelligences, from swarms to cognitive robotics. Here we present the latest evolution of a continuously developing cognitive control architecture (pCAMAL). The CAMAL (Computational Architectures for Motivation, Affect, and Learning) model is a theoretical construct for investigating artificial minds that draws on formal (BDI) reasoning, probability models, affective computation, reactive machines and self-configurable architectures. The latest implementation (probabilistic CAMAL or pCAMAL) has been developed using both synthetic and real robots. It combines qualitative and quantitative reasoning in a sense, motivator management, goal selection, action feedback cycle to adapt to environments.

Abstract: Impedance control is a practical feedback control scheme for a class of mechanical systems whose dynamics are regarded as a linear dynamical system with a specified linear input-output relation. Such a linear dynamical system is said to be passive if and only if its input-output transfer function is positive real. For a class of nonlinear mechanical systems including robotic mechanisms, the passivity is still in effect and further a strict passivity concept can be introduced with the aid of a nonlinear version of Kalman-Yakubovich-Popov relation. Notwithstanding the strictness of passivity, strict positive realness (s. p. r.) has not yet studied so far for any class of nonlinear dynamical systems. This paper aims at introducing an extended notion of s. p. r. property for a class of robotic mechanisms with input-output pairs specified in task space (or operational space). A sufficient condition for a task space PD (position and its differential) feedback to make the closed-loop system s. p. r. in a local sense is given by analyzing what optimality condition the closed-loop system satisfies. The optimality is shown on the basis of solvability of a Hamilton-Jacobi-Bellman equation derived from an optimal regulator problem. It is shown that task-space impedance control with optimality and s. p. r. property is realizable even if the degrees-of-freedom (d. o. f.) of an objective mechanism is redundant relative to the dimension of task space. This suggests a new understanding of Bernstein’s dexterity of human limb motion under some d. o. f. redundancy.
