Abstract This paper describes a case-study in the design of electromechanical systems with distributed actuators and sensors. A hierarchical mechanical architecture and the corresponding control system architecture is described with specific reference to paper handling systems within copiers and printers. General issues pertaining to the design of such systems are highlighted along with specific solutions. The paper concludes with a discussion of the lessons learnt from the design experience and its applicability to the general problem of concurrent mechanical and control system design of modular electromechanical systems.

In the paper, basic problems connected with designing optimal structure of control Unmanned Surface Vehicle USV used for a harbour protection were presented. A specificity of USV operation during carrying out protection tasks forces different view on hardware structure of the system and a process of taking decisions than during carrying out other tasks. Correct determination of the both factors have deciding influence on an effectiveness of carried out by the vehicle in this case mission.

Structure Topology

A hybrid optimization strategy for integrated topological optimization design of piezoelectric cylindrical flat shell structure is proposed. The method combines the genetic algorithm (GA) and linear-quadratic-regulator (LQR) theory to optimize the performance of coupling structure/control system. The GA is used to choose the optimal structure topology and number and placements of actuators and control parameters; meanwhile, the LQR is used to design control system to suppress vibration of optimal structure under sinusoidal excitation, which is based on the couple-mode space control. In addition, the mathematical morphology operators are used for repairs of disconnected structure topology. The results of numerical simulation and computations show that the proposed method is effective and feasible, with good performance for the optimal and coupling piezoelectric cylindrical shell structure/control system.

Main Components

LaB6 emitters are becoming increasingly popular as direct replacements for tungsten filaments in the electron guns of modern electron-beam instruments. These emitters offer order of magnitude increases in beam brightness, and, with appropriate care in operation, a corresponding increase in source lifetime. They are, however, an order of magnitude more expensive, and may be easily damaged (by improper vacuum conditions and thermal shock) during saturation/desaturation operations. These operations typically require several minutes of an operator's attention, which becomes tedious and subject to error, particularly since the emitter must be cooled during sample exchanges to minimize damage from random vacuum excursions. We have designed a control system for LaBg emitters which relieves the operator of the necessity for manually controlling the emitter power, minimizes the danger of accidental improper operation, and makes the use of these emitters routine on multi-user instruments.Figure 1 is a block schematic of the main components of the control system, and Figure 2 shows the control box.
