Motor efficiency depends upon power factor
Advances in motor control algorithms and cost-effective electronic components for implementing motor
drives are creating a revolution in virtually every electric motor market. Control of the power factor in an
efficient manner also means less lost energy, both in the motor and drive electronics.

Motor Control/Sensors
Designing high-performance and power-efficient motor control systems
This paper provides an overview of motor control design considerations, such as control of multiple motors, field-oriented control, power factor correction and sensorless control. It also addresses how today's microcontrollers (MCUs) bring even greater precision, power efficiency and reduced cost to a wide range of applications.

A Matter of Torque: Electric power steering systems
Electric power steering offers greater vehicle safety by adapting variable steering ratios to human needs. In addition, it can make cars lighter and more fuel efficient compared to those using hydraulic steering systems. The central electronic elements of power steering systems are 32-bit microcontrollers (MCUs). Since power steering is a safety-critical function, it also requires new MCU elements that support the functional safety of the overall system. This article provides an overview how Power Architecture based MCUs can be used in power steering applications. Innovative elements, such as the cross-triggering unit for motor control and fault collection unit for monitoring safety critical signals, are explained.

Industrial Instrumentation
Applying embedded design to develop an intelligent solar tracking system
Solar panels are typically in fixed positions. They're limited in their energy-harvesting ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy systems, the solar panels should be able to align with sunlight as it changes during a given day and from season to season. This article examines the design advantages of creating an intelligent solar tracking system using an embedded processor and an FPGA in a system-on-a-chip (SOC) architecture.
Powering Reliability - Ensuring Automotive Quality beyond AEC Q100/101
The increasing complexity of electronic systems in modern automobiles reached a level where a paradigm shift both in design and the qualification process becomes mandatory. Releasing products according AEC-Q101, a sampling based method derived from ammunition testing in the 1940s and implemented in the 1960s for automotive, is absolutely insufficient to support a zero defect strategy. The combined use of state-of-the-art design tools and methods for robustness validation allows designers to cope with these challenges

This 3-part series will explore real-time high performance computing with the usage of embedded multi-core processors. Part 2 outlines software architecture approaches for utilizing multi-core processors, along with cache optimizations.
Digital representations of analog systems for control system applications
This tutorial shows how digital controllers can be created from an analog (or continuous) model. Included is an examination of the "Tustin's method" and "hold equivalence" methods of converting from the analog to digital domain.
Applying Chaos Theory to Embedded Applications
A unique chaotic-expansion formula that can be used to approximate chaotic sequences, and where the coefficients of the expansion formula are matched to the sequence through linear determination.

Replacing RS-232 with 802.11n wireless
The RS-232 serial interface is used extensively in industrial environments, but there is a lot to gain from the replacement of these cables with a wireless transport mechanism. In this article we consider how a wireless link based on 802.11n WLAN can be configured and deployed for this purpose.
