Title: Electric precipitator starting method and starting device
Inventor: TOMIMATSU KAZUTAKA
IPC: B03C3/66
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To enable starting an electric precipitator in a short time and safely when starting it in a high humidity atmosphere. SOLUTION: A controller 6 intermittently applies DC high voltage to an electrode 2 by a DC high voltage power source 5 on start-up. A condenser C1 installed in a DC high voltage applying circuit is quickly charged with electricity by DC high voltage, but the electrical charge thereof is discharged by circuit resistance or the like after the voltage is cut off, and the terminal voltage is lowered in order according to a damping time constant. When an electrode 2 part is insufficiently insulated, the damping time constant of voltage is short and the electric charge of the condenser C1 is discharged in a short time and base voltage is not raised to standard voltage limits. When the electrode 2 is satisfactorily insulated, the damping characteristics are long and the base voltage is raised to the standard voltage limits.  Therefore, when the base voltage is within the limits, the insulation of the electrode 2 part is judged to be restored, and charge of the electrode 2 is switched to continuous charge to shift the device to stationary operation.

Title: Control device for control system having sliding resistance
Inventor: HIBINO RYOICHI
IPC: G05B13/02
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To improve controllability and to hold a high robust property in the case of controlling a control system having sling resistance by using a sliding mode controlling method. SOLUTION: The control device finds out a deviation between the practical value of status quantity allowed to follow a set point and the set point (step 1), calculates a switching plane σ from the found deviation (step 2), finds out a corrected switching plane σ' by adding a carrier wave being a periodical function like a sine wave and a saw-tooth-wave and having a finite value in the inclination of its waveform to the calculated switching plane σ(step 3), and outputs a manipulated variable (u) on the basis of the value of the corrected switching plane σ' (step 4).  Since the manipulated variable (u) is similar to that to be used for a normal sliding mode controlling method when the switching plane σ does not exist in the vicinity of a value '0' and is to be periodically changed similarly to a dither signal when the switching plane σexists in the vicinity of the value '0', the deterioration of controllability with respect to sliding resistance can be prevented and a robust property excellent in the control of a sliding mode can be held.
