Model-based predictive control (MPC) is a widely used technique for controlling highly interactive and complex refinery and chemical operations. MPC applications typically generate massive amounts of information that may be difficult for operators to assimilate and understand. An expert system provides an excellent interface to organize and handle these large amounts of data. Some examples in which an expert system can be used in conjunction with MPC include comparison of predicted operating conditions to current operating conditions;detection of sensor faults;communication of operator messages, rules, and goals;predictive alarming;and multiple constraint handling.

The need for low-cost, high quality and application-targeted spaceborne sensing is rapidly gaining in prominence. In response to this need, Spar Aerospace Limited is a major contributor to PROGERT, a Quebec-Government funded project to enhance remote sensing services to the provincial forestry user community. The computer simulation of advanced electro-optical concepts is being performed at Spar in PROGERT and applied to the development of a new satellite imaging instrument. As part of the overall design strategy, Spar is developing a model, based on forest physical parameters and standard sensor sub-systems. The purpose of this model is to explore system-level trade-offs in the early design phases thus reducing costly hardware development. In particular, the use of this model allows optimal specification of data acquisition parameters within the constraints of mission and end-user requirements.

The compatibility of optical fiber time domain (OFTD) sensors with aircraft optical communications systems is discussed. The OFTD sensors are multiplexed using serial and parallel formats that allow three dimensional strain and temperature mapping. The optical fibers used in these sensor arrays are similar, if not identical, to those used in aircraft optical communication data buses. A 100/140 mu m core/cladding diameter silica (glass) fiber using a high temperature resistant polyimide protective coating is employed. This multi-mode (MM) fiber format is typical for short-haul local area networks (LANs) used in aircraft. Furthermore, the 100/140 mu m optical fiber is compatible with commercially available fiber optic connectors, splices, splitters, and other peripheral hardware. This opens up the possibility for hybrid fiber optic communication/sensor networks either embedded in or attached to aircraft structures. Results are presented on tests performed with prototype sensors using the 100/140 mu m MM fiber type. These sensors were embedded in composite laminates that are representative of materials used in advanced technology aircraft. Structural strain was monitored and compared with data gathered through conventional means (strain gages and extensometers). Future applications and possibilities for advanced field trials which combine the OFTD sensor concept with existing fiber optic data buses on aircraft are also proposed.< >

Recently the Time Delay Control (TDC) method has been proposed as a promising technique in the robust control area, where the plants have nonlinear dynamics with parameter variations and substantial disturbances are present. TDC method, however, requires the measurements of all the state variables, together with their derivatives. This requirement imposes a severe limitation on the applications to most real systems. In order to solve this measurement problem, we proposed an observer design method that can stably reconstruct the state variables and their derivatives. Then, for a simulation study, the controller/observer based on our design method has been applied to a nonlinear plant, the result of which confirmed that the controller/observer performs satisfactorily as predicted. Finally we made experimentations on a DC servo motor that is subject to substantial amount of inertia variations and external disturbances. The results showed that the controller/observer performs quite robustly under those variations and disturbances, and is much less sensitive to sensor noise than the controller using numerical differentiations.

Diode lasers offer the potential of a low-cost, compact, and efficient source for imaging laser radar applications. However, to date, there are no commercially available high-power cw sources that can be collimated into a low divergence beam. In this paper, we show that it is possible to use surface emitting distributed feedback diode laser arrays in conjunction with micro-optics lens arrays to assemble a laser source with approximately 10 W output power and sub-milliradian beam divergence.

Hughes Danbury Optical systems (HDOS) has developed and flight tested a unique GaAs laser radar which produces high resolution 3-D imagery of the terrain beneath the aircraft. This line scanner is described along with the design parameters used to develop the current model. Improvements planned for the sensor include the addition of an IR channel which would be used to provide passive imagery for target cueing. This would have the effect of reducing the system processing requirements while simultaneously increasing the probability of detection and reducing the false alarm performance.
