On Certain Least-Squares Synthesis Methods Misconceptions
George H. Sutherland · Journal of Mechanical Design · 1979
This paper shows a fundamental flaw in previously published linear superposition least-squares synthesis techniques. These techniques have the desirable noniteration characteristic. However, this paper shows, by a reformulation of the method, that they are based on a false premise. Numerical results bear this out. A Lagrange-multiplier technique is suggested as a superior alternative.
