Draw the block diagram of a system using proportional control and feedforward command compensation, for the plant 1/(4s2 + 6s + 3). Determine the transfer function of the compensator. Discuss any practical limitations to its use.

LECTURE – 1 MECHANICS Study of what happens to a body when forces are applied to it. Mechanics Rigid bodies Deformable bodies Fluids (Don’t change shape) (Do change shape) Compressible Incompressible Statics Dynamics Fundamental physical Quantities Length Mass Time Force Newton’s second Law relates these quantities through the formula F = ma F = Force applied to object m = mass of object a = acceleration of object 2 different unit systems Standard English
