The present invention provides a highly efficient fuel cell power supply unit, which is constructed by directly connecting a fuel cell with a capacitor. In this power supply unit, a control device of the unit calculates the output voltage V2 of the fuel cell after the variation of electrical load based on the synthetic current-voltage characteristics of the fuel cell and the capacitor and the predetermined width of the variation of electrical load ΔI, calculates the corresponding current Ifc2′, and then calculates the equilibrium reacting gas supply amount Qa1, and supplies an excess amount of the reacting gas exceeding Qa1 before the variation of electrical load.

In the fuel cell (FC) system comprising a FC and a rechargeable battery, a demand power of the FC is calculated by subtracting the charge power to the battery from a demand power signal which indicates the demand value of a load current and using the result. Accordingly, the charge current is never supplied to the battery which is charged to the maximum ratio, which prevents the utilization ratio of the fuel cell from decreasing and which prevents the battery from overcharge. On the other hand, the battery which is discharged to the minimum ratio does not output the discharge power but the charge power is supplied to the battery. Accordingly, it prevents the battery from over discharge.

In order to improve the fuel consumption efficiency of the fuel cell vehicles, a control flow is provided, in which, first, it is determined whether the vehicle speed VST is lower than a predetermined speed ISTP (step S01), whether a motor output PMCMD including the driving motor and the motor for driving the air compressor is less than a predetermined motor output ISTPPM (step S04), whether the brake is in the ON state (step S05), and whether the terminal voltage Vst of the power storage unit is higher than predetermined values VISTPH and VISTPL (step S06). When all of the determinations are “YES”, a permission flag for executing the idle stop F_ISTP is set to “1”, and if any of them is “NO”, the permission flag F_ISTP is set to “0”.

Hydrophobic inorganic fine particles are provided which: does not cause melt adhesion of toner to a photosensitive member and contamination of a contact charging member; imparts excellent flowability, charging performance and durability to toner even after the toner is stored in a high-temperature, high-humidity environment over a long time period; and does not cause dripping of toner and contamination with the toner. The hydrophobic inorganic fine particles are obtained by subjecting inorganic fine particles to surface treatment with silicone oil and then with a silane compound and/or a silazane compound, or by subjecting inorganic fine particles to surface treatment with a silane compound and/or a silazane compound in the presence of silicone oil, and further subjecting the inorganic fine particles thus surface-treated to surface treatment with silicone oil.

摘要:
An adaptive controller using an adjustment law expressed in recurrence formula, including a plant, a controller which controls an input to the plant, and a parameter adjuster which adjusts a parameter of the controller. In the controller, an input to the parameter adjuster is multiplied by a coefficient other than 1 such that the range of change of the parameter adjuster's internal variable is restricted to a predetermined limit. With this arrangement, the controller can be realized on a less expensive and fewer-bit-length microcomputer such as 16-bits. The input to the parameter adjuster may be made up of the control input to the plant and an output therefrom. Alternatively, the input to the controller and an output from the plant may be both multiplied by a coefficient other than 1 to be input to the parameter adjuster. Further, it may be arranged such that a gain matrix element of the parameter adjuster is intermittently replaced with a prescribed value when it exceeds a limit, or when the cycle of the control exceeds a predetermined number of cycles.
摘要:
A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates a controller parameters .theta.. The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The air/fuel ratio sensor outputs are sampled and one of the sampled data is selected as the air/fuel ratio to be input to the adaptation mechanism. Similarly, the senor outputs are sampled and one of the sampled is selected in accordance with another characteristic to be used in the estimation of the air/fuel ratios of the individual cylinder. The air/fuel ratio is discriminated to be within a prescribed range, and set to a predetermined value when it is determined to be within the prescribed range.
