From the Back Cover
Modeling and Control of Antennas and Telescopes presents the author’s research and field experience in the area of antenna modeling, dynamics, and control. The required spacecraft tracking accuracy of 1 mdeg was the impetus for the new approaches to the antenna controls that use model based controllers (LQG and H¥ ). Consequently, modeling also required a new approach using system identification techniques. Most of the material presented is new in the telescope industry. The methods have been not only analyzed and tested, but actually implemented, giving confidence in the final result, which is significantly increased antenna pointing accuracy.
The author explains two different approaches to telescope modeling: analytical and experimental. The analytical approach combines the structural and drive model, using Matlab and Simulink. The experimental, uses the test data to obtain the equations of the antenna model. Both models are excessively large and the model reduction techniques included make the model size small enough for the controller design purposes. The book also covers the wind models based on the wind tunnel data (steady-state), and on the field data (gusts) since wind gusts are the main antenna disturbance.
The book shows the PI and feedforward controller tuning and their performance as a benchmark for measuring the pointing improvement when the LQG and H¥ are implemented. The properties, performance, and tuning of the LQG and H¥ are also presented. The material explains the nonlinear control issues such as velocity and acceleration limits, friction, and backlash. It also covers RF beam control techniques (scanning and monopulse), and the open loop control of the track level unevenness.
Modeling and Control of Antennas and Telescopes serves as a useful reference for students and engineers in the area of antenna modeling, dynamics, and control.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to moluna, Greven, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
