摘要： This disclosure relates to a static inertia compensation function generator for use in a constant tension control system for a d.c. drive motor operating to wind or unwind a reel of material. A first generator develops a signal D which is a function of the normalized instantaneous diameter of the reel. A second generator receives the signal D and generates a signal Alpha 1K1D2 which is a function of the square of the normalized instantaneous diameter, Alpha 1 and K1 being constants. An inverter also receives the D signal and delivers an inverted normalized instantaneous diameter signal -D. A third generator receives the inverted signal -D and develops a signal, 1/D2 which is a function of the normalized instantaneous diameter squared. A summation amplifier receives the two signals: - Alpha 1K1D2 and 1/D2 and delivers an amplified inertia compensation signal Iac Alpha 2( Alpha 1K1D2 + (1/D2) where Alpha 2 is the gain of the amplifier. The inertia compensation signal Iac is additive or subtractive from a current reference I and is used for accelerating or decelerating the d.c. motor for the purpose of maintaining constant tension on the material under dynamically varying load conditions.

摘要： A sensing system for cut-to-length shear, for providing a shear control signal for a process line of material moving at a line speed which is a function of a voltage VL, the shear control signal being used for causing actuation of the shearing mechanism. A signal VB is derived which is a function of the predetermined cut length. A signal Vi is derived which is a function of the instantaneous length of material passing the shearing mechanism. An additional voltage Delta V is derived is a function of (VL tinertia/t) where tinertia is the time required for the shearing mechanism to respond to the shear control signal, and t is the running time required for a predetermined cut length to pass through the shearing mechanism at maximum line speed. The signals VB, Vi and Delta v are received by electronic circuitry, and a shear control signal is delivered to the shearing mechanism when the algebraic relationship is satisfied VB Vi + Delta V.

摘要： A torque compensation system is disclosed for d.c. motor drives using field weakening for speed control. A diode switching matrix and a static divider are connected so that the divider receives signals which are functions of motor armature current and speed respectively, and delivers at its output a signal which is proportional to motor torque for adjusting the speed reference to the motor.
