Title: Control method for chaos
Inventor: ICHIKAWA HIROSHI
IPC: A61N1/362
Filed: 1994-03-17
Abstract: PURPOSE:To shorten the time from the actuation of a chaos system to the start of control by an OGY method by correcting control parameters on the basis of a learning result so that a chaos track approaches a target period track. CONSTITUTION:Once the chaos system 10 begins to be operated, a coordinate detection device 13 detects state point coordinates xsin each time the chaos track crosses Poincarel section. The coordinates xsin detected by the device 13 are sent to a neural network in a 1st parameter control unit 11 before the chaos track approaches the target period track until the control by OGY method becomes possible. The neural network outputs a parameter correction quantity DELTAPn' for approaching the chaos track to a target period point for the inputted coordinates xsin. The device corrects the parameters of the system 10 on the basis of the correction quantity DELTAPn'. Consequently, the chaos track can speedily approaches the target period track after the system 10 is actuated.

IPC: G06F12/16
Filed: 1990-02-28
Abstract: PURPOSE:To eliminate the increase of time needed for diagnosis of a memory despite increase of the number of memory banks by giving the same address and the same data to plural memory banks and writing and reading simultaneously data into and out of each memory bank to decide the coincidence among these data. CONSTITUTION:The same addresses and data are given to the memory banks 2a - 2d and then written simultaneously there by the data writing means 1, 6 and 3a - 3d. Meanwhile the data reading means 1, 5 and 3a - 3d read simultaneously the data out of the banks 2a - 2d. Then a comparison means 4 compares the data read out of the banks 2a - 2d with each other for each bit and decides the coincidence or discordance of them. In such a constitution, all other memory banks can be simultaneously diagnosed after the diagnosis is through with a certain memory bank. Thus it is possible to extremely shorten the memory diagnostic time and to keep the same diagnostic time despite increase of the number of memory banks.
