Abstract: Modern motion control systems are more and more acting as “agents” between skilled human operator and environment (robot assisted surgery, microparts handling, teleoperation, etc.). In such situations design of control should encompass wide range of very demanding tasks. At the lower level one should consider tasks of controlling individual systems - like single DOF systems, motor control, robotic manipulator or mobile robot. On the system level control of bilateral or multilateral interaction between systems of the same or different nature, the remote control in master-slave systems, haptics etc. should be considered. Such a complexity of motion control system functions poses a challenge for control systems designers due to the diversity of the tasks and changing structure of the system and the interaction with environment. In general design of motion control system should take into account (i) unconstrained motion - performed without interaction with environment or other system, (ii) motion in which system should maintain its trajectory despite of the interaction with other systems, (iii) constrained motion where system should modify its behavior due to interaction with environment or another system or should maintain specified interconnection - virtual or real - with other system and (iv) in remote operation control system should be able to reflect the sensation of unknown environment to the human operator. In this talk we will discuss different frameworks for complex motion control design for unconstrained and constrained motion - when system moving without obstacles, or is in contact with environment or another system or has certain functional interaction with another system. The problems related to bilateral and multilateral systems, maintenance of virtual relation among mobile robots and control of haptic systems will be discussed.

Abstract: The application of innovative technologies of automatic control in lighting systems gains daily the interest of engineers, constructors and users. The main purpose of these applications is the energy savings. Daylight control is a form of automatic control that replaces the manual control of the users. The core of this system is the photosensor, which creates a signal in proportion to the amount of the daylight that detects, using its spatial and spectral response. The signal of the photosensor can be combined with dimming electronic ballasts which adjust the electric light output giving a great potential for energy savings in areas with high levels of daylight.

Nevertheless, the daylight responsive systems are widely misunderstood and they have been characterized hastily as problematic systems. The lack of knowledge and comprehension of these systems is a great withdraw against their widespread use and a lost opportunity for energy savings. In this present study becomes effort to overcome these difficulties clarifying the operation procedures of the photosensors and their function as part of the lighting system. Also techniques for their evaluation are proposed through an analysis of experimental data of the characteristics that influence their operation and advices for their optimum placement in spaces of application.
