State space control of frequency standards
نویسنده
چکیده
Discrete time control systems are widely used in time and frequency applications. Control systems can be designed to reduce phase and frequency offsets to a given reference either more or less aggressively depending on overall system needs. There are many methods available to aid in designing control systems, including techniques based on state space system models. Several state space control design methods will be shown. The control concepts covered in this paper are pole placement, minimum control effort, and linear quadratic Gaussian. The effects of steering limits on system performance will also be discussed.

Provision of car parking space in the residential neighborhoods: A development control challenge in urban areas
Although a substantial body of research concurs that most urban areas have a challenge in providing adequate car parking space, there is a scarcity in the literature on how conformity to planning standards that regulates the provision of car parking spaces may be analyzed. This study, therefore, examines the extent to which the planning standards that regulate compliance with the provision of c...
