    Self-contained systems providing control and navigation for vehicles of all kinds use gyroscopic elements to maintain reference directions with respect to inertial space. Sensors for resultant gravity field and inertial reaction forces along input axes determine the vertical and also linear velocities with respect to inertial space. These components divided by an equivalent Earth radius transfer the motion to Earth coordinates in which integration gives location. Corrections for Earth's rotation projected in and perpendicular to the horizontal plane are made as computed cosine and sine projections of Earth's angular velocity. Current systems result with the order of fractional miles per hour performance. View full abstract»

    In this paper we study the effect of dynamic behavior of the market on the optimum pricing policy for a revenue maximizing firm in a monopoly market. We show that the optimum pricing policy in the dynamic market can be very different from the static one, and the most important contributing factors for this difference are: consumer response time, planning period and the discount rate. Furthermore we show that for the linear model that we use, in the limit of infinite planning horizon or market equilibrium the optimum price for the dynamic market reduces to the optimum price for the static market.

    A session at the 1981 JACC in Charlottesville was devoted to the development of two test examples for adaptive control. The two candidate processes were derived by two panelist pairs from the aerospace (Franklin and Stein) and the chemical process (Foss and Monopoli) control domains. The purpose was to distill those process characteristics suggesting application of adaptive control and to provide practically meaningful test examples for comparison of various adaptive schemes. This article presents the proposed benchmark models and encourages reader participation in the second "edition" of this panel discussion to be presented as session TP1 on Thursday, December 17, 1981,at the 20th CDC in San Diego.

    We describe four computer packages for interactive computer-aided design of control systems. DIGICON (digital control) is a computer aid to the design of digital controls for single-input single-output (SISO) systems using the state-space techniques of pole and zero assignment. CONCON (continuous control) is a similar package for the design of SISO continuous systems using the same techniques. The program DOPTICON (discrete optimal control) is a computer aid for the design of discrete optimal control systems using the linear quadratic Gaussian (LQG) theory and OPTICON (optimal control) is its continuous-time counterpart. All four packages contain algorithms for computation of the poles and zeros of the resulting designs as well as the evaluation of the transient responses. View full abstract»
