IPC: H03F1/32
Filed: 1978-02-10
Abstract: PURPOSE:To perform stable kdistortion compensation for a long time, by providing the level adjuster between the predistorter circuit for distortion compensation and the compensated amplifier, and controlling the level adjuster depending on the gain variation of the compensated amplifier. CONSTITUTION:The compensation amount is greatly varied with the gain and position variation of the compensated amplifier. For example, the region to realize the compensating amount more than 25 dB is within + or - 0.8 dB for gain variation and within + or - 2.5 degrees for the phase variation. Accordingly, the means compensating the gain variation of the amplifier at the input is very effective to the distortion compensation. The signal distributed from the disributors 21 and 22 is monitored with the gain variation detector 23 and the level adjuster 16 is controlled depending on the variation and the input level of the compensated amplifier 13 is controlled, allowing to cancel the gain variation. Further, the gain variation of the amplifier is due to temperature, the level adjustment due to temperature detection can also be effective.

Title: Load weight estimating method
Inventor: KATO TETSURO
IPC: B23Q17/00
Filed: 1995-01-05
Abstract: PURPOSE: To estimate the load weight and perform proper feedforward control as to a body attached additionally to a controlled system. CONSTITUTION: The load weight is estimated as to a tool fitted to the tip of the arm of a six-axes robot. The robot begins to be moved first according to a proper operation program. Adaptive control is performed for 4th-6th axes (step S1). At adaptive control convergence time (step S2), estimated moments gr4-gr6 of the 4th-6th axes and the estimated load inertia J5 of the 5th axis are stored (step S3). An additional weight estimation equation is solved as to m6, x6g , y6g , and z6g by using those data and the respective axis values θ3 -θ6 of the robot and parameters m5 , s5z , l5z , J5m, g, etc., and the result is stored (step S4). When the robot reaches an end point position (step S5), the robot is stopped and the processing ends. The found parameters of the load weight are used to calculated feedforward terms when subsequent feedforward control is performed.
