This paper describes the use of a fast iterative analog computer to study a sophisticated communications system. This system uses amplitude modulated orthogonal polynomial waveforms as carrier signals.

A magnetically levitated high speed vehicle on an elevated periodically supported guideway is approximated by a single-mass vehicle on a flexible single and double span beam with rigid piers. To describe the distributed parameter system of the flexible guideway, modal analysis technique is used....

This paper describes the application of an analogue computer to the design of control systems when constraints are imposed on the variables of the system. The operation of the computer is fully automatic, so that manual adjustment of parameter settings is completely eliminated. The performance...

A complete continuous-system simulation package written in PASCAL graphically exhibits the anatomy and requirements of simulation software in general, and also the very real advantages and disadvantages of programming in PASCAL. To combine PASCAL's neat program/data structures and useful...

It has been shown that time invariant third order plants can be time optimally controlled by a hybrid computer. The computer generates a time optimal switching surface, which it then uses to control the plant. [1]

This note analyses the problem of stability of hybrid simulation of dynamic systems. Time delays and sample-and-hold operations do cause serious stability problems, and if frequently happens that considerable time and effort are wasted because instability is not known in advance of programming...
