Automatic Control System An automatic control system is a preset closed- loop control system that requires no operator action. This assumes the process remains in the normal range for the control system. An automatic control system has two process variables associated with it: a controlled variable and a manipulated variable. A controlled variable is the process variable that is maintained at a specified value or within a specified range.

In this manner, the step-wise rotation of the rotor can be synchronized with pulses in a command-pulse train, assuming, of course, that no steps are missed, thereby making the motor respond faithfully to the input signal (pulse sequence) in an open-loop manner. a) The measurement system in a feedback control system is situated in the feedback path of the control system. b) It can be shown that sensitivity of a control system to parameter changes in the measurement system is direct.

A tube in an aircraft control system that transmits a torsional force from the operating control to the control surface. Bell cranks are normally used in aileron controls and in the steering system of nosewheels.. A fairlead is a device to guide a line, rope or cable around an object, out of the way or to stop it from moving laterally . The fairlead may be a separate piece of hardware, or it could be a hole in the structure.

Consider the discrete time stochastic control system described by the following equations:. i ) p ij , where p ij 0 and. 0 , system (2.1) is said to be. mean square bounded. ([12]) Give constant matrices Y = Y T 0 and X Z . mean square boundedness for (2.1).. (3.2) then unforced system (2.1) is. mean square bounded.. From (3.1), we have. Hence, because of (2.2), we obtain.

INTRODUCTION Nowadays, comparing with the field oriented control (FOC), direct torque control (DTC) is known as a simpler and easier scheme to perform . With DTC technique, the instantaneous values of flux and torque are estimated from the stator voltages and currents in order to comparing with the command values.

Thus we have simple timer devices where a chemical pump is activated based on system operating time, control systems where a chemical pump is activated whenever the system blows down based on conductivity, and makeup proportional systems where a chemical pump is activated based on addition of a set amount of makeup to the cooling system 1 .
