Abstract This paper introduces an experimental recursive method for simultaneously changing both the mechanical structure and control design of mechatronic systems in order to improve the system’s overall performance. The method improves a system’s closed-loop control specifications through recursive concurrent structure reinforcement and control gain optimization. By using a process of structural reinforcement, a single prototype structure can be used repeatedly until the system performance goals are achieved. To determine the optimal incremental structure changes, a recursive algorithm based on a gradient descent method and a parameter estimation theory is employed. After the incremental structure reinforcements are applied, the control parameters are optimized with respect to multiple control specifications. Next, the resulting system incorporating the structure and control changes is tested and compared with the desired level of performance. The entire process consisting of experimental evaluation, data analysis, and structure reinforcement is repeated until the system performance achieves the desired level. Simulation experiments are successful in changing both the structural and control parameters of a simplified positioning system and show improvement in the system’s overall settling time.

Dual-bypass MIG welding (DB-GMAW) is a new kind of high speed MIG welding with three arcs. In order to monitor the weld process and control it, a high speed weld system of DB-GMAW was built. The system was run by LabVIEW programs, including getting data of system and control output signals. The test result of system showed that all equipments could be used in the same time. Beside images of weld pool and arc, the weld voltages and currents of every part had been acquired. The signals of bypass current and weld speed also had been input TIG welding sources and worktable motor successfully. Meanwhile, the high speed weld formation had a good quality, and all of these established the closed-loop control of high speed DB-GMAW.

We design the navigation and control system for unmanned aerial vehicle (UAV) with four tilting rotors. The considered UAV implements the so-called X-sceme, which implies the main body and four symmetrical beams, upon which rotors with propellers are mounted. It is different from the classical quadrotor by having four additional servomotors that may change the orientation of the rotors with respect t the main body, thus increasing the control parameters number. Greater number of the actuators in the system, on the one hand, opens new venues for UAVs’ applications but, on the other hand, makes the mathematical model of the UAV’s dynamics quite complicated. The latter calls for new control algorithms to be developed. We start by forming the mathematical models of the UAV’s dynamics. It is shown that the introduction of the tilting motors allows implementing independent control of the quadrotor’s position and attitude. The control loop is designed on the base on the analytical dynamics inversion. The expressions for the control parameters thus obtained are subjected to the numerical analysis, which allows taking into account technical constraints for maximal motor speed and tilt angles. Feedback in the control loop is implemented by simulation of the on-board sensors’ signals, whose characteristics correspond to those of the sensors used in the UAV’s experimental prototype design. The signals are processed with the aid of the unscented Kalman filter algorithm. The results of numerical experiments corroborate the efficiency of the developed control and navigation algorithms. The mission simulated in the numeric experiments is tracking of a pre-defined trajectory and pointing with a body-fixed camera at a mobile object, which, in turn, moves along a programmed trajectory.The results of the numeric experiments show that the UAV is capable of performing complex maneuvers with independent position and attitude control.

To respond to changes in the requirements of the information and control system, it is necessary to rebuild the system with new functions and/or systems with a different architecture. In this paper, we propose a method that enables on-site technicians to perform step-wise migration from a legacy system to a target system without having to stop the whole system and without requiring advance preparation or support from a system engineer who is an expert in system design and development. Accordingly, we aimed to develop a technology for the coexistence of and cooperation between with target and legacy systems and cooperation test between heterogeneous systems. We implemented this method and evaluated its effectiveness by applying it for rebuilding a production line management system.
