MN-7 MINIATURE NONLINEAR ELECTRONIC SIMULATOR
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
The MN-7 nonlinear, electronic simulator is an analog mathematical machine, designated for investigating the dynamics of systems and objects of automatic control, the motion of which is recorded by ordinary differential equations, having a small amount of nonlinear dependencies. For the solution of more complex nonlinear systems, the parallel work of two or more such devices is possible. A solver unit, an I-5 electronicbeam indicator and an ESV-6 power unit are included in the MN-7 electro-simu or. There are 16 DC amplifiers in the solver unit, which perform the operations of integration, differentiation, summation and scale conversion. The amplifiers have a three-cascade system, a static power coefficient without reverse communications of approximately 40,000, a transmission band during negative reverse communication of approximately 150 c and zero drift of 5 mv after 10 minutes. The solver unit has eight diode elements, which, at collective switching with amplifiers, permit simulation of an ambiguous or discontinuous function of the hysteresis loop, dry friction, zone of insensitivity.
