Title: Magnetic disk device
Inventor: NOGUCHI TAKASUKE
IPC: G11B21/10
Filed: 1992-04-27
Abstract: PURPOSE:To diminish a steady speed deviation and to control a rush speed upon a changeover from a speed control mode to a transient control mode and to enable a high speed seek by integrating an error signal and adding it to a voice motor when a speed error of a magnetic head becomes smaller than a prescribed value. CONSTITUTION:Under a seek mode, a moving speed of the magnetic head 1 and its position are detected by detecting parts 9 and 11 respectively, and a target speed corresponding to a residual moving distance of the magnetic head 1 calculated by a control part 7 is read out of a table 13, and a speed error signal is outputted. When a difference between the target speed and the detected speed is large, a switch 17 is opened to make a speed control system function as a P-control system, and when the difference becomes lower than a prescribed threshold, the switch 17 is closed and the speed error signal is integrated by an integrator 19, a position error signal is generated and sent to an adder 23. In this case, the speed control system becomes a PI control with a position control system as a minor loop. By this method, no steady speed deviation is generated, and the accurate control of the rush speed at the time of the changeover from the speed control to the transient control is feasible.

Filed: 1995-04-07
Abstract: PURPOSE: To carry out a trouble foreseeing diagnosis exactly without mis-judgement while the load of an engine is changed by finding out an exhaust pressure representative value at every cylinder of the engine, the differential between the cylinders and the dispersion of the differential and foreseeing the trouble based on the dispersion. CONSTITUTION: CPU 11 samples data from a basic signal by every certain hour on the output of an exhaust pressure sensor 14 and calculates an exhaust pressure average value as a value representing the exhaust pressure per cylinder based on a sampled value. Then, a standard deviation is calculated as the dispersion of the exhaust pressure average value per cylinder. It is judged whether this standard deviation is bigger than the value multiplied the standard deviation by a prescribed abnormality judging threshold value or not and if it is YES, it is judged that abnormality is generated in a gas engine. The change of the exhaust pressure average value between adjacent cylinders is calculated and the standard deviation is calculated as the dispersion of this change and compared with the basic deviation and it is judged whether it is a load change or abnormality.
