摘要： PROBLEM TO BE SOLVED: To establish a synchronous bivariate controller for avoiding the occurrence of overspeed. SOLUTION: The two-variable controller for a motor-driven rotary machine comprises a two-control variable setter 3 for generating a control target speed with a control target position X1 as a variable; a position control value calculator 5 for calculating a position control value X3 for controlling the position of a servo motor, based on the positional deviation of the target position X1 and a detection position X2; a speed control value calculator 2 for calculating the speed control value V2 for controlling the speed of the servo motor, based on the speed deviation of the speed X1 and the speed detected value V2; and a speed controller 9 for performing the speed control of the servo motor, based on the position control value X3 and the speed control value V3. The calculator 2 calculates the second value V3 in which the speed of the servo motor is not directed in the acceleration direction as the speed control value, when the speed deviation is positive. The two variables of the position and the speed are combined, and the speed of the position and the speed is preferentially controlled. The real speed may not exceed the control target speed.

摘要： PROBLEM TO BE SOLVED: To allow molding a stable resin product without quality fluctuation despite change in work environment, in injection molding using an electric injection molding apparatus.
SOLUTION: The invention relates to an electric injection molding apparatus which injects and fills up a resin material, supplied to an injection cylinder, into dies 1 and 2, by back and forth driving an injection screw 23 equipped in the injection cylinder using a motor 29A. A control means 50A, which speed controls the motor 29A when filling the resin material in dies 1 and 2 and pressure controls the motor 29A when compensating post-filling resin contraction, is switched from speed control to pressure control, when pressure in dies 1 and 2 detected or presumed by an internal pressure detector reaches a predetermined pressure. This brings the pressure in the die, to a smooth and continuous state, thereafter to a gradually increasing condition, then to a raised medium-pressure state, and further to a gradual decrease afterward.

摘要： PROBLEM TO BE SOLVED: To control multiple screw output within a proper control output range. SOLUTION: This multiple screw control system is constituted so as to form a power correction signal on the basis of a first position control signal Is1 formed based on a common speed command value X0 and an output difference signal, a first power control signal Id1 formed based on the first position control signal Is1, a second position control signal Is2 formed based on the speed command value X0 and the difference signal and a second power control signal Id2 formed based on the second position control signal Is2. The power correction signal is formed by employing a value calculated by subtracting a secondary difference signal, which is the difference between the difference between the first power control signal Id1 and the second position control signal Is2 and the difference between the second power control signal Id2 and the first position control signal Is1, from the first power control signal Id1. The multiple screw output is controlled within the proper control output range on the basis of the secondary difference signal. COPYRIGHT: (C)2005,JPO&NCIPI
