2 Motor Control Systems and Design
Introduction
More Stringent Energy Regulations Drive Motor Control InnovationsIn today’s expanding industrial marketplace, the demand for electrical power is growing at an unprecedented rate . More than 40% of that electrical demand comes from industrial electric motors of all sizes . Because of that phenomenon, governments and certification agencies worldwide are introducing new regulatory legislation and more stringent energy efficiency requirements on electric motor OEMs and end users . Like many great technological innovations, there needs to be a pressing demand in the market for change .
Analog Devices recognized years ago that this new era of smarter and highly efficient motor control systems would be the new standard for the motor control industry . As part of that recognition, ADI embarked on an integrated and comprehensive motor control design program in collaboration with our strategic partners, who are experts in their respective fields (MathWorks,® ARM,® Boston Engineering,® IAR Systems,® and Xilinx®), aimed at addressing the entire system architecture to achieve the greatest level of efficiency while improving system accuracy and reliability .
By taking a system-level view (see Figure 1) of these new challenges, ADI was able to develop products that not only exceeded the individual performance specifications but also represented the optimal interface between other functional blocks of the circuit . This system solution approach enables ADI to offer industrial-based customers a completely integrated solution that fits their specific needs while helping them meet the new, more stringent energy regulations .

Isolated Gate Drivers
Overcoming Limitations of Optocouplers and High Voltage Gate Driver Solutions
Isolated gate drivers provide electrical isolation as well as strong gate drive capability, which is often required for safety and robustness in many system architectures . The isolated gate driver portfolio from Analog Devices offers designers performance and reliability advantages over designs utilizing optocouplers or pulse transformers . Utilizing ADI’s proven iCouplertechnology, the isolated gate driver family offers the advantage of a maximum propagation delay of 50 ns, less than 5 ns channel-to-channel matching, a 50-year lifetime for 400 V rms working voltage, and galvanic isolation in a single package .

The isoPower Difference
Nonisolated Interface DevicesAnalog Devices offers a wide range of RS-232, RS-422, and RS-485 transceivers to suit many applications . The RS-232 specification allows for reliable data transmission from one transmitter to one receiver at data rates of up to 20 kbps over relatively short distances (up to 50 feet) . On more recent RS-232 transceiver chips, data rates of up to 1 Mbps are achievable over shorter distances (up to 5 feet) . The RS-485 specification meets the requirements for a truly multipoint communications network, while the RS-422 specification satisfies simplex multidrop standards .

Current Sense AmplifiersCurrent sense amplifiers are used when a shunt resistor is placed in the high side or low side and high accuracy over temperature is required in harsh environments . In motor control, normally the bidirectional capability will be needed . In order to build fast and accurate control loops, the step response time and common-mode voltage step immunity are critical .

Difference AmplifiersDifference amplifiers can be used for voltage and current sensing in motor control systems because they can reject very high common-mode voltage . They will enable the low voltage converters to interface with the high voltage industrial environment . This is especially true when functional isolation is needed . Excellent drift and CMRR are the advantages of ADI’s difference amplifiers .

Precision Op AmpsPrecision op amps are used as signal conditioning in the motor control systems . They will be used as the sensor to ADC interface, thus the rail-to-rail input and output in high linearity will be needed . They can also be used between the resolver-to-digital converter (RDC) and the resolver to provide high current in high slew rate and accuracy . Wider bandwidth amplifiers will be used to detect the fast changing current in the system .

Low Noise MEMS Accelerometers for Condition Monitoring
MEMS accelerometers are finding their way into condition monitoring products due to several attractive attributes, not the least of which is lowering the overall cost of the system . MEMS sensors bring small size and weight, low power, a dc response for fast recovery from overload, high shock tolerance, highly integrated solutions, and, maybe most importantly, scalable manufacturing .

Model-Based Design — Making Design Easy
System Design Value for Any Motor Control SystemModel-based design was developed to help simplify the difficulties and complexities inherent in control systems designs using traditional nonautomated methods . Model-based design provides the designer with a virtual design environment that enables developers to use a single model of their entire system for data analysis, model visualization, testing, validation, and eventually product deployment . Once the model is built and tested, accurate real-time software is automatically generated, saving time and reducing overall development costs as compared to traditional manual coding . Model-based design with automatic code generation can also be used in rapid prototyping, further reducing the design cycle . By its nature, model-based design provides a structure for software reuse that permits established designs to be effectively scaled up or down in complexity depending upon the desired application and reliably upgraded in a more simplistic and cost-effective manner .
Model-based design saves valuable design resources by cutting design time and providing final designs that are more accurate and more closely approximate predesign expectations for performance, systems functionality, and features and schedule .
Benefits X Faster design iterations that produce desired
performance, functionality, and capabilities
X Design cycles that are more predictable and result in faster product shipments
X Reduction in design, development, and implementation
