SUMMARY
Moving the summation block in control systems affects the equation's structure significantly. When the summation block (H3) is placed before the gain block (G1), the entire result of the summation is multiplied by G1, altering the expression to (V1 - V3*H3) * G1. This contrasts with the original expression, V1*G1 - V3*H3, where the term V3*H3 remains independent of G1. Understanding this relationship is crucial for accurate control system modeling.
