Franklin , J. Powell , and A. Author : Gene F. Chapter 4 on A First Analysis of Feedback has been substantially rewritten to present the material in a more logical and effective manner. A new case study on biological control introduces an important new area to the students, and each chapter now includes a historical perspective to illustrate the origins of the field.
Author : William S. Every aspect of control is expertly covered, from the mathematical foundations to applications in robot and manipulator control. Never before has such a massive amount of authoritative, detailed, accurate, and well-organized information been available in a single volume.
Absolutely everyone working in any aspect of systems and controls must have this book! Author : Charles M. It includes detailed modeling of mechanical, electrical, electro-mechanical, thermal, and fluid systems. Models are developed in the form of state-variable equations, input-output differential equations, transfer functions, and block diagrams.
The Laplace-transform is used for analytical solutions. Author : Bela G. Retaining the format that made the previous editions bestsellers in their own right, the fourth edition of Process Control and Optimization continues the tradition of providing quick and easy access to highly practical information. The authors are practicing engineers, not theoretical people from academia, and their from-the-trenches advice has been repeatedly tested in real-life applications.
Expanded coverage includes descriptions of overseas manufacturer's products and concepts, model-based optimization in control theory, new major inventions and innovations in control valves, and a full chapter devoted to safety.
From the …rst three equations, slove for V1; V2. Find the equations and transfer function for the biquad circuit of Fig. The torque constant of a motor is the ratio of torque to current and is often given in ounce-inches per ampere. The electric constant of a motor is the ratio of back emf to speed and is often given in volts per rpm. In consistent units the two constants are the same for a given motor. What is its torque constant in ounce-inches per ampere? Some remarks on non SI units.
Actuall, the ounce is a unit of mass, but like pounds, it is commonly used as a unit of force. If we translate it as force,. The electromechanical system shown in Fig. The system consists in part of a parallel plate capacitor connected into an electric circuit. Capacitor plate a is rigidly fastened to the microphone frame. Sound waves pass through the mouthpiece and exert a force fe t on plate b, which has mass M and is connected to the frame by a set of springs and dampers.
It is acceptable to leave in nonlinear form. A very typical problem of electromechanical position control is an electric motor driving a load that has one dominant vibration mode. The problem arises in computer-disk-head control, reel-to-reel tape drives, and many other applications.
A schematic diagram is sketched in Fig. The motor has an electrical constant Ke , a torque constant Kt , an armature inductance La , and a resistance Ra. The rotor has an inertia J1 and a viscous friction B. The load has an inertia J2. The two inertias are connected by a shaft with a spring constant k and an equivalent viscous damping b.
Write the equations of motion. For the robot in Fig. Determine the dynamic equations relating the speed of the robot with respect to the torque command of the servo. Your equations will require certain quantities, e. Assume you have access to whatever you need. That is, a system where the torque is applied by a motor on a gear that is simply accelerating an attached gear, like the picture in Fig. In order to multiply the torque by a factor of 2, the motor must have a gear that is half the size of the gear attached to the wheel, i.
If the wheel was not attached to the robot, Eq. So that means we need to add the rotational inertia of the two other wheels and the inertia due to the translation of the cart plus the center of mass of the 3 wheels. The acceleration of all these quantities are directly related through kinematics because of the nonslip assumption.
That means, if we neglect the translation inertia of the system, the equation becomes. When you apply a torque to a drive wheel, that torque partly provides an angular accelation of the wheel and the remainder is tranferred to the contact point as a friction force that accelerates the mass of the vehicle.
That friction force is. So the end result is:. Using Fig. Solution: Equation 2. Adding the spring torque to Eq. A precision-table leveling scheme shown in Fig. The system input is vi and the system output is d: Type 1 Type 2 Type 1. New to this edition are: much sharper pedagogy; an increase in the number of examples; more thorough development of the concepts; a greater range of homework problems; a greater number and variety of worked out examples; expanded coverage of dynamics modelling and Laplace transform topics; and integration of MATLAB, including many examples that are formatted in MATLAB.

Cloth January pp. This revision of the textbook on feedback control with the associated web site, www. Chapter 4 on A First Analysis of Feedback has been substantially rewritten to present the material in a more logical and effective manner.
A new case study on biological control introduces an important new area to the students, and each chapter now includes a historical perspective to illustrate the origins of the field. Finally, some of the more exotic topics have been moved to the web site. Digital control is treated early on. The book provides enough information, early and simply, so that a student could implement a controller in a digital computer, and an instructor could cover it in one lecture.
With this approach, students will understand how control systems are being implemented in most cases today, and instructors will have a method of teaching modern design and implementation at an undergraduate-level course. The authors focus on design as a theme early on and throughout the entire book. This book illustrates real-world problems and applies techniques from earlier chapters. It also brings together the classical and state-space techniques with discussions of the relative strengths and their role in design.
Unique to this book is an entire chapter devoted to case studies covering real problems in a variety of fields that draw on all the design methods covered in the book.
