The deflection of the spring which may be measured by a linear-motion potentiometer is a direct measure of acceleration.
The freebody diagram is shown in Fig.

The robot arm is a set of serial links with the beginning of each link jointed with the end of the preceeding link in form of a revolute joint (for relative rotary motion between the two links) or a prismatic joint (for relative translatory motion).T fat 9 Jdtz or T dtz fdt 9 (213) Equation (2.13) is a linear constant coefficient differential equation describing the dynamics of the system shown in Fig.The block diagram of such a system with single feedback loop is illustrated in Fig.The last two forms are in fact alternatives and can be interconverted by a single differentiation or integration.Consider now that a load torque TL is applied at the output as indicated in Fig.The first automatic control system, the y-ball governor, to control the speed of steam engines, was invented by James Watt in 1770.When an epidemic disease affects this community the social pattern is altered as shown in Fig.45- 82 9(2-ad w(rad/ sec J(kg-m T(newton-In) K(newton-m/ rad newton-In per rad/ sec) Fig.Assuming that the lateral control system and the vertical control system are independent (decoupled we shall consider only the lateral control system whose block diagram is given in Fig.
In these control systems signals in certain parts of the plant are in analog form.
