The control unit of a printer feeds paper P from a paper supply path 12 to a main conveyance path, drives a paper feed roller pair, conveys the paper in a first direction through the main conveyance path, and prints on the first side of the paper P. After printing on the first side ends, the conveyance direction changes from the first direction to the opposite second direction, and the medium is back-fed to a looped inverting conveyance path at a faster conveyance speed than the conveyance speed when printing. First and second conveyance rollers are then driven to convey the print medium at high speed through the inverting conveyance path, thereby inverting the front and back and returning the medium to the main conveyance path for printing the second side.

The invention discloses a path planning and swing reduction control method of a four-rotor variable-rope-length hanging system, comprising the following steps: establishing a mathematical model of the four-rotor and a swing model of the suspended load; The state of the rotor and the load is constrained, and the parameters of the spline curve are calculated according to the constraints to obtain the planned path; according to the obtained planned path, the minimum transit time that satisfies the constraints of the swing angle is obtained by using the bisection method; The level control method realizes the precise positioning of the load and the suppression of the swing angle of the load by tracking the planned path, and the load is delivered to the predetermined position in the shortest time. The method disclosed in the present invention enables the entire hoisting system to reach the desired position from the initial position in the shortest time by planning a suitable plane motion trajectory, while keeping the swing angle of the load within a small range, which not only improves the Transportation efficiency, but also to ensure the safety of transportation.

The present application relates to a method and system for self-learning of oil octane number. The method includes the following steps: dividing the knock intensity coefficient of the engine into three knock intensity levels: low, medium and high; Knock intensity level; count the number of knocking occurrences of low, medium and high knock intensity levels in each cylinder of the engine; judge whether the octane number of the engine oil satisfies the self-learning condition; when the self-learning condition of the oil octane number is satisfied, the engine Oil octane number self-learning update. The embodiments of the present application provide a method and system for self-learning of the octane number of an oil product. In an engine control system, a learning method for identifying the octane number of an oil product is designed, and the knocking intensity is divided into three different knocking levels. In the case of grades, the octane number of the oil is reduced to different degrees, and the recognized octane number is used as the adjustment input of the ignition advance angle control, thereby reducing the probability of engine knocking and reducing the damage to the engine caused by frequent knocking.

The invention discloses a method for vaguely predicting, compensating and controlling tower top temperature during desulfurization of sintering flue gas. Aiming at the problem that the tower top temperature cannot be stably controlled due to the influence of system time delay and external disturbance during desulfurization of the sintering flue gas, the method comprises the following steps of: building a prediction model of the tower top temperature by using a heat transfer mechanism; designing a vague prediction and compensation controller of the tower top temperature by taking the difference between a prediction value and a set value as input; and compensating water injection quantity by using model rule. By the method, main disturbance in a system is introduced into the prediction model, and a compensation value is calculated according to the difference between the prediction value and the set value, so the problems of poor stability of the system caused by large fluctuation of disturbance factors and the time delay of the system are solved.

A travel control apparatus includes: a detection device configured to detect an object ahead in a travel direction of a vehicle; and a vehicle control device configured to perform a vehicle control in which the object is regarded as a control reference when a lateral movement speed of the object is directed to a travel lane of the vehicle, wherein even when the lateral movement speed of the object is directed to the travel lane of the vehicle, when the object is detected in right and left ends of a detection range of the detection device, the vehicle control device prevents the vehicle control.
